Abstract (sommario):

Tire/Road noise is a dominant contribution to a vehicle interior noise. In this paper, we present the process we developed to support automotive OEMs with road noise engineering during vehicle design and development. The process uses blocked forces identified from measurements performed on a single tire installed on a test stand. The forces are then combined with vehicle level transfer functions to predict the sound at the driver ears. The results are imported in a driving simulator for NVH to allow for auralization and sound quality evaluations. The process can be applied from the very early stages of the vehicle development using CAE simulation results and allows to evaluate the vehicle road noise performance long before the first prototype is available.

Abstract (sommario):

ABSTRACT Optimization is a key tool used by automakers to efficiently design and manufacture vehicles. During vehicle design, much effort is devoted to efficiently simulate and optimize as many vehicle parameters as possible to save development costs during physical testing. One area of vehicle development that heavily relies on physical testing and subjective driver feedback is the tire design process. Optimizing tire parameters relies either on this subjective feedback from trained drivers, or use of existing tire data or scaling of a reference tire model simulate the desired design change and provide feedback. These data are often difficult to obtain and properly scale to represent the appropriate design changes. Michelin's TameTire model is a force and moment tire model. It includes thermal tire effects and is physically derived, thereby allowing quick access to scaling factors to change a tire's behavior based on pertinent tire design changes such as tread depth and tread stiffness. In this paper, a multi-objective optimization is performed to observe the trade-off between tire wear and handling performance by using the scaling factors available in the TameTire model.

Abstract (sommario):

Special software for tire vulcanization simulation was developed using ABAQUS software as the core solver and Visual Basic6.0 as the develop language. The software was based on principles of easy operation, professional and intelligent analysis. In this way, automation and professionalization of the analysis process were performed. The special software mainly consists of three functions: Firstly, model grid was automatically recognized, and corresponding configuration files were automatically built, which were required in the analysis preprocess. Secondly, ABAQUS solver was invoked to solve the model. Finally, results such as state-of-cure, temperature and other curing performances were automatically extracted and saved as excel or word format. Besides, the curing profiles could be proposed. The results showed that this software is easy to use and work efficiently.

Abstract (sommario):

Abstract The modern development process of winter tires not only requires intense subjective and objective evaluation of the tire properties on the vehicle, but also requires knowledge about the influence of relevant tire characteristics on vehicle driving behavior. It is important to understand the influences of ambient conditions, such as temperature, track surface (asphalt vs corundum) and tire inflation pressure on tire behavior. Tire characteristic results of a parametric study, using a fully climate-controlled interior drum test stand will be presented. The effect on tire characteristics and the resulting vehicle behavior will be discussed using vehicle dynamics simulation. Furthermore the consequences for an optimal design of modern high performance winter tires will be presented.

Abstract (sommario):

ABSTRACT Tire tread wear is a key issue in the tire development process and for tire customers. In order to measure the wear performance, tire manufacturers usually proceed to wear tests and calculate the tire life from those tests. An important point in this tire life computation is the criteria chosen for defining the tire's end of life. In Europe, there is a legal minimum tread depth set to 1.6 mm applicable to 75% of the tread pattern width. However, outside those 75% (i.e., on the shoulder part), no clear and shared limit is defined. Also, the usual behavior of customers to decide when their tires should be changed is not well known. The goal of this 2012 study was to identify an average worn profile of tires in Europe and the behavior of customers for replacing their tires. For that, 3000 tires worn out by customers have been collected in scrapyards and measured in five European countries. In this article, we will present the tire collecting method, the measurement process, the analysis method, and some general results and statistics on this 3000 tire database. Finally, the method to compute the average end of life profile and the resulting profile is given.

Abstract (sommario):

The paper addresses a modelling procedure to automatically generate 2D finite element meshes of tires, together with the assignment of material property. A program is developed based on the secondary development of HyperMesh with TCL/TK language, thus achieving the automatic FE modelling starting from the AutoCAD tire cross-section profile. The model created as input file can be exported into ABAQUS directly. By automatizing the modeling process, the program can significantly reduce the modeling time and improve modeling efficiency.

Abstract (sommario):

ABSTRACT Increasing vehicle performance requirements and virtualization of the development process require more understanding of the physical background of tire behavior, especially in transient rolling conditions with combined slip. The focus of this research is the physical description of the transient generation of tire lateral force and aligning torque. Apart from tire force and torque measurements, two further issues were investigated experimentally. Using acceleration measurement on the tire inner liner, it was observed that the contact patch shape of the rolling tire changes nonlinearly with slip angle and becomes asymmetric. Optical measurement outside and inside the tire has clarified that carcass lateral bending features both shear and rotation angle of its cross sections. A physical simulation model was developed that considers the observed effects. The model was qualitatively validated using not only tire force and torque responses but also deformation of the tire carcass. The model-based analysis explained which tire structural parameters are responsible for which criteria of tire performance. Change in the contact patch shape had a low impact on lateral force and aligning torque. Variation of carcass-bending behavior perceptibly influenced aligning torque generation.

Abstract (sommario):

Aircraft tire retread is the process of retreading or reconditioning aircraft tires after being used several times for take off and landing. Retreading an aircraft tire can be done many times, which is between 3-5 times depending on the level of wear of the tire layer. Data from INACA ‘Indonesia AviationOutlook 2017’ shows that the number of jet aircraft owned by Indonesian airlines for Wide Body is 23 aircraft and Narrow Body is 338 aircraft. Where the number of aircraft tyre in the Nose Landing Gear / NLG and Main Landing Gear / MLG Wide Body aircraft are 55 EA and 216 EA respectively, while for Narrow Body aircraft each is 352 EA and 1488 EA. The available information states that tire retreading needs in Indonesia are around USD 20 million per year. There is a huge opportunity in the need for retreading aircraft tires owned by Indonesian airlines, which is around USD 20 million per year, with 10% growth per year, so the next 5 years will reach around USD 30 million. However, this opportunity cannot be taken by MRO Indonesia because MRO Indonesia does not have the ability to retread airplane tires. The cause of the inability to take up an aircraft tire retreading business opportunity is partly because there is no government policy support to encourage aircraft tire manufacturers to collaborate with Indonesian investors to build a tire retread facility, there is business competition with aircraft tire retreading in Malaysia and Thailand, businesses most only think solely of big profits, and the unattractive business climate in Indonesia such as complicated licensing, inefficient supply chains and incentives provided are less attractive. The steps needed to capture the opportunity to retread aircraft tires are to carry out continuous campaigns and incorporate aircraft tire retread facilities development programs into the National Strategic Program and the Aerospace Industry Roadmap.

Abstract (sommario):

A significant annual growth in the number of spent car tires creates a serious environmental problem and calls for the need to continue searching for efficient resource-saving methods of their recycling. There is a growing number of efforts aimed at studying waste tire thermochemical conversion processes, including their pyrolysis to obtain valuable products, including a solid fraction (coke residue), liquid hydrocarbon fraction (pyrolysis oil), and noncondensable gaseous fraction (pyrolysis gas). Commercial and pilot pyrolysis plants and reactors are reviewed. A rotating drum reactor, shaft and screw reactors are the most promising solutions for implementing a continuous process. The development of new resource-saving solutions for the pyrolysis of waste tire requires knowledge of the thermal characteristics of this process, including information on the material and heat flows in the pyrolysis reactor. The composition and thermal properties of waste tire, as well as specific outputs, composition and fuel properties of pyrolysis product material flows, including pyrolysis gas, pyrolysis oil and coke residue, are presented. Information on the pyrolysis plant or reactor heat balance structure is either absent or incomplete. Based on the data available in the literature, the heat balance of a commercial pyrolysis plant equipped with screw reactors characterized by a specific thermal destruction heat of 0.640 MJ/(kg of tires) is drawn up and studied. The numerical analysis results correlate with the data published for the commercial-grade plant. Information on the pyrolysis chamber heat balance structure is correct enough for use in engineering practice. It has been found that the specific heat consumption for the pyrolysis process is 2.269 MJ/(kg of tires). This value can be used in numerically analyzing pyrolysis plants equipped with other designs of pyrolysis reactors.

Abstract (sommario):

Le pneu est fortement impliqué dans les performances d'un véhicule. La consommation de carburant du véhicule (résistance au roulement, aérodynamisme), le bruit, le confort, la tenue de route et la sécurité sont liés au pneumatique choisi. En utilisant des mesures objectives, il est possible de prédire certaines de ces caractéristiques, mais pour d'autres comme la manipulation, nous ne pouvons pas vraiment prédire l'évaluation subjective faite par des pilotes d'essai expérimentés. La méthodologie essai/erreur est parfois appliquée pour identifier le potentiel des pneus et évaluer les performances des pneus en fonction de conceptions et de caractéristiques mécaniques spécifiques.Aujourd'hui, dans l'industrie automobile, l'évaluation des performances de conduite des véhicules et des pneus est encore largement réalisée sur une base subjective par des conducteurs d'essai expérimentés. Ceci est justifié par le fait que la perception par les clients des performances du véhicule est également subjective et qu'aucune relation fiable n'a été trouvée pour relier les mesures objectives des performances à la perception humaine des performances.Une revue de littérature approfondie sur l'objectivation de l'évaluation subjective, l'interaction véhicule-conducteur, la simulation de la dynamique du véhicule et l'analyse de données multivariée exploratoire ainsi que les tests d'hypothèses statistiques est la première étape de la recherche visant à étudier les méthodologies, l'analyse des données et les outils statistiques. utilisé par d'autres chercheurs.Sur la base de la revue de la littérature, la thèse propose une méthodologie qui permet de traduire des évaluations subjectives en métriques objectives (environnement véhicule ainsi qu'environnement véhicule-pneu) permettant la prédiction du résultat d'un test subjectif en utilisant des mesures objectives conduisant à une réduction de les itérations au cours du processus de développement du pneu. Le choix de la complexité du modèle de dynamique du véhicule le plus pertinent décrit les principales caractéristiques mécaniques du pneu affectant les performances de tenue de route et leur effet sur les métriques objectives d'intérêt.Des manœuvres expérimentales spécifiques de la dynamique du véhicule ont été sélectionnées pour cette étude dans le but de dévoiler la complexité de l'évaluation subjective de la maniabilité sans être simpliste et en prêtant attention à l'interconnexion des différentes variables et à leur interaction avec les facteurs contextuels.Dans le cadre de l'étude de corrélation mentionnée ci-dessus, le rôle du conducteur dans le système conducteur-véhicule est étudié. Les résultats présentés montrent qu'avec la méthodologie choisie, il est possible de mieux comprendre la stratégie de test du conducteur en identifiant les principales réponses du véhicule affectant toutes les étapes de l'évaluation subjective.Pour approfondir et renforcer la compréhension du rôle du conducteur, deux études de panel impliquant des conducteurs professionnels et non professionnels ont été réalisées. Celles-ci ont permis l'étude et l'analyse de l'interaction véhicule-conducteur en termes de proprioception et de vision, d'influences audiovisuelles et de séquelles en mouvement
The tire is heavily involved in the performance of a vehicle. Vehicle's fuel consumption (rolling resistance, aerodynamics), noise, comfort, handling and safety are related to the tire chosen. By using objective measurements, it is possible to predict some of those features but for some others like handling we cannot really predict the subjective evaluation made by experienced test drivers. Trial/error methodology is sometimes applied to identify tire potential and to gauge the tire performance related to specific designs and mechanical characteristics.Today, in the automotive industry, the evaluation of vehicle and tire handling performance is still largely performed on a subjective basis by experienced test drivers. This is justified by the fact that customer perception of vehicle performance is also made subjectively and, no reliable relationship has been found to relate objective performance measures to the human perception of performance.An extensive literature review on the objectification of subjective assessment, the vehicle-driver interaction, the vehicle dynamics simulation and the explorative multivariate data analysis as well as statistical hypothesis testing is the first research step aimed to investigate the methodologies, the data analytics and statistical tools used by other researchers.Based on the literature review, the thesis proposes a methodology that allows to translate subjective evaluations into objective metrics (vehicle environment as well as vehicle-tire environment) enabling the prediction of the outcome of a subjective test by using objective measurements leading to a reduction of the iterations during the tire development process. The choice of the most relevant vehicle dynamics model’s complexity depicts the main tire mechanical features affecting the handling performance and their effect on the objective metrics of interest. Specific experimental vehicle dynamics maneuvers have been selected for this study with the aim of unpacking the complexity of the subjective handling assessment without being simplistic and paying attention to interconnectedness of the different variables and their interplay with contextual factors.In the frame of the above-mentioned correlation study, the role of the driver in the driver-vehicle system is investigated. The results presented show that, with the chosen methodology, it is possible to gain insights on the driver’s testing strategy identifying the main vehicle responses affecting all the stages of the subjective evaluation. To deepen and strengthen the understanding of the driver’s role, two panel studies involving professional and non-professional drivers have been carried out. Those allowed the study and analysis of the vehicle-driver interaction in terms of proprioception and vision, audio-visual influences and aftereffects in motion

Abstract (sommario):

This research has examined the cost estimating and cost modeling research literature and identified the benefits and limitations of existing practices. Particular emphasis has been placed on the methods available for developing cost models at the early stages of product and process development where data from which to develop models is scarce. Shortfalls in existing practices have been identified as well as potential methods of resolving these limitations. Of these methods Virtual Manufacturing appears to offer the greatest potential for resolving issues with lack of data availability by enabling such data to be generated. Detailed trials have, therefore, been undertaken to examine the effectiveness of Virtual Manufacturing in terms of its ability to generate valid data in the quantities required to ensure accurate cost models can be developed. In addition, the research has involved the use of Data Mining techniques to identify the cost estimating relationship's within the data output from the Virtual Manufacturing trials. Here the aim has been to investigate the potential use of Data Mining techniques to fully automate the data analysis stage of the cost model development process.

According to the Packard Commission, "Unreasonably long acquisition cycles -- ten to fifteen years for major weapon systems is a central problem from which most other acquisition Problems stem." Since the commission issued its report in 1986, the time required to develop new military systems has only grown. This research and its recommendations are intended to identify and eliminate the causes of those long development times for military systems. This report addresses a key factor in determining the development time for military projects: the project's initial schedule. Part 1 outlines the current situation, previous efforts to reduce development time, and experiences with cutting development time in the commercial sector. It also documents the military product development process. Part 2 identifies a key area--the schedule development process, and its impact on development time--for in-depth research. Through understanding what is driving the initial project schedule and the impact of the initial project schedule on the eventual development time, the author identifies key drivers of development time. Part 3 presents the results of three surveys and analyzes the processes used to develop a project's initial schedule, the process used to develop a contracted schedule, and the impact of these schedules on actual development time. Part 4 presents observations, draws conclusions, and makes specific recommendations for remedial action. The key barriers to reducing development time for military systems are the lack of importance placed on project schedules; the lack of effective schedule-based information and tools; the lack of schedule-based incentives; and the overriding impact of the funding-based limitations on defense projects. The steps necessary to establish a focus on reducing development time are: 1) recognizing the impact of development time, 2) providing the necessary information for decision makers, 3) providing proper incentives at each organizational level, and finally providing a structure to effectively managce the set of all development projects to ensure that each project can be funded based on its development related requirements. Implementing the recommendations and focusing on reducing development time will force other changes in the acquisition process. The focus on reducing the time to develop and field systems will drive the acquisition system to better meet the needs of our warfighters, more rapidly, and at lower cost. Better, Faster, and Cheaper. Even more importantly, shortening development times is critical to develop and produce with limited resources, the right weapons at the right time to deter or to defeat any potential enemy at any time with the minimum cost to our warfighters.

Speed and flexibility in product development will be the differentiators that determine which companies will have competitive advantages in the next decade. To this end, many authors have advanced frameworks and tools for streamlining product development processes, all with the objective of reducing the time required to engineer and deliver a quality product. Frameworks such as concurrent engineering describe what the process should evolve to, while tools such as cross-functional teams address implementation. But one element that has not been clearly addressed is the measurement and improvement of the development process during the pursuit of this goal. The focus of this thesis is on the design of an approach to improve the product development process, based on applying established process improvement techniques and project simulation. The objective of the improvement effort is to increase control over development lead time. Achieving this control promotes efficient product development by allowing the development team to: i) improve speed and flexibility, and ii) confidently evaluate the trade-off between them when necessary. A "Voice of the Customer" study of the product development process at a large American automobile manufacturer was used to determine inhibitors of this control and efficiency. Considering the relationship between these inhibitors, three improvement efforts were identified: ** Track and address the causes of delay ** Optimize schedule recovery actions, and ** Develop a more representative measure of project progress. To implement these efforts, two tools are discussed. A delay tracking framework was designed to collect and analyze activity delays. This analysis focuses the reduction of controllable causes of delay and aids in the determination of the efficacy of schedule recovery actions. A project simulation was used to illustrate the expected effects of implementing the three improvement efforts. The simulation can be used to generalize the learnings from tracking delay to aid in making project management decisions. More specifically, the use of the simulation for evaluating schedule recovery actions and the effect of proposed changes in design requirements is discussed.

Abstract (sommario):

The purpose of this master thesis is to improve the quality of software testing in a large company developing real-time embedded systems. Software testing is a very important part of software development. By performing comprehensive software testing the quality and validity of a software system can be assured. One of the main issues with software testing is to be sure that the tests are correct. Knowing what to test, but also how to perform testing, is of utmost importance.

In this thesis, we explore different ways to increase the quality of real-time testing by introducing new techniques in several stages of the software development model. Four complementary methods are suggested. The proposed methods are validated by implementing them in an existing and completed project on a subset of the software development process. The original output from the completed project is compared with the new output.

The presented results from the validation are positive in the sense that it is shown that the test stage was more qualitative, mostly due to a higher level of quality on input from earlier stages.

Abstract (sommario):

A major application of computers has been to control physical processes in which the computer is embedded within some large physical process and is required to control concurrent physical processes. The main difficulty with these systems is their event-driven characteristics, which complicate their modelling and analysis. Although a number of researchers in the process system community have approached the problems of modelling and analysis of such systems, there is still a lack of standardised software development formalisms for the system (controller) development, particular at early stage of the system design cycle. This research forms part of a larger research programme which is concerned with the development of real-time process-control systems in which software is used to control concurrent physical processes. The general objective of the research in this thesis is to investigate the use of formal techniques in the analysis of such systems at their early stages of development, with a particular bias towards an application to high speed machinery. Specifically, the research aims to generate a standardised software development formalism for real-time process-control systems, particularly for software controller synthesis. In this research, a graphical modelling formalism called Sequential Function Chart (SFC), a variant of Grafcet, is examined. SFC, which is defined in the international standard IEC1131 as a graphical description language, has been used widely in industry and has achieved an acceptable level of maturity and acceptance. A comparative study between SFC and Petri nets is presented in this thesis. To overcome identified inaccuracies in the SFC, a formal definition of the firing rules for SFC is given. To provide a framework in which SFC models can be analysed formally, an extended time-related Petri net model for SFC is proposed and the transformation method is defined.

Abstract (sommario):

Background: The business model (BM) is an essential part of firms and it needs to be innovated continuously to allow firms to stay or become competitive. The process of business model innovation (BMI) unfolds incrementally by re-designing or developing new activities in order to provide value propositions (VP). With increasing availability of data, pressure on BMI to orchestrate their activities towards putting data as a key resource and develop data-driven business models (DDBM) is growing. Problematization: The DDBM provides valuable possibilities by utilizing data to optimize current businesses and create new VPs. However, the development process of DDBMs is outlined as challenging and scarcely reviewed. Purpose: This study aims to explore how a data-driven business model development process looks. More specifically, we adopted this research question: What are the phases and activities of a DDBM development process, and what characterizes this process? Method: This is a qualitative study in which the empirical data was collected through 9 semi-structured interviews where the respondents were divided among three different initiatives. Empirical Findings: This study enriches the existing literature of BMI in general and data-driven business model innovation in particular. Concretely, this study contributes to the process perspective of DDBM development. It helps to unpack the complexity of data engagement in business model development and provides a visual process model as an artefact that shows the anatomy of the process. Additionally, this study resonates with value logics manifestation through the states of artefacts, activities, and cognitions. Conclusions: This study concludes that the DDBM development process is structured with two phases as low data-related and high data-related activities, inheriting seven sub-phases consisting of different activities. Also, this study identified four underlying characteristics of the DDBM development process comprising value co-creation, iterative experiment, ethical and regulatory risk, and adaptable strategy. Future research: Further work is needed to explain the anatomy and structure of the DDBM development process in different contexts to uncover if it captures various complexities of data and increases its generalizability. Furthermore, more research is required to differentiate between different business models and consequently customizing the development process for each type. Future research can also further explore the value co-creation in developing DDBM. In this direction, it would be interesting to consider connecting the field of open innovation to the field of DDBM and, specifically, its role in the DDBMs development process. Another promising avenue for future research would be to go beyond the focus on merely improving the VP to maximize the data monetization, and instead focus on the interplay and role that data has on sustainability.

Abstract (sommario):

For military all-terrain vehicles, there is a need to radically increase tactical and operational mobility through new modalities by fundamentally improving vehicle terrain control. By characterizing the tire relaxation length and time constants for lateral and longitudinal dynamic changes, mobility control can be enhanced to accommodate agile tire dynamics. This paper analyzes the transient period of the tire reaction force development process, which is characterized by the relaxation length, for the purpose of agile tire dynamics control as a pre-emptive, fast and exact response of a tire to dynamic changes of its interaction with terrain. In this regards, a comprehensive literature review was undertaken and the tire relaxation length was analyzed for different types of vehicles and their operational velocities. The time relaxation constants, which are derived from the relaxation length, are determined and analyzed based on the data gathered in technical literature. Based on the analysis, reference magnitudes of the time relaxation constants are proposed to be used in agile tire dynamics control algorithm and hardware developments of military all-terrain vehicles.

Abstract (sommario):

Virtual testing is a new engineering development trend to design, evaluate, and test new engineered products. This research proposes a virtual testing framework for new product development using three successive steps: (i) statistical model calibration, (ii) hypothesis test for validity check and (iii) virtual qualification. Statistical model calibration first improves the predictive capability of a computational model over a calibration domain. Next, the hypothesis test is performed under limited observed data to see if a calibrated model is sufficiently predictive for virtual testing of a new design. A u-pooling metric is employed for the hypothesis test to measure the degree of mismatch between predicted and observed results while considering uncertainty in the u-pooling metric due to the lack of experimental data. The calibrated model can be rejected only when the measured metric of the calibrated model strongly suggest that the null hypothesis—the calibrated model is valid—is false. If the null hypothesis is accepted, the virtual qualification process can be executed with a qualified model for new product developments. The qualification process builds a design decision matrix to aid in rational decision-making on the product developments. A computational model of a tire tread block was used to demonstrate the effectiveness of the proposed framework.

Abstract (sommario):

In the automotive industry, the need to meet the durability requirements in a very early stage of the development of a new vehicle model is becoming more and more crucial. This is a key factor that can reduce the time to market and avoids modifying substantially the design if a component fails earlier than expected. This is also a challenging task for several reasons; in the early phase the primary design suffers from a lack of knowledge about the loads that the new vehicle will experience in its life. In literature ([1][2][5][6][7]) several methods have been proposed; for instance the so-called digital test track approach ([1]) is a CAE-based tool in which the vehicle and the road are modeled in a multibody environment together with a detailed representation of the tire and the driver in order to perform a replication of a test drive. This predictive method is very valuable but still requires a lot of information about the vehicle’s components that is usually not available at this stage of the vehicle development. On the other hand a pure test-based procedure suffers from other problems such as the need of a mule vehicle and long and costly test campaigns that need to be repeated at each component’s modification. A hybrid approach has then been proposed and implemented successfully by LMS on industrial size cases. This approach known as Time Waveform Replication (TWR) ([2]) relies on a set of test data and multibody model available from test drives carried out on a predecessor or a vehicle similar to the one that is being currently designed. The data collected on a road test is used to back-calculate the equivalent spindle displacements that will cause the same forces on the multibody model that are experienced in the test sessions. This approach has several beneficial aspects with respect to the two mentioned before. The tire model does not need to be accurate since the displacement are applied directly to the spindles (but the application can be easily extended to “road profile identification” if a detailed tire model is available). Moreover it is well known that if the forces measured at the spindles are applied directly to the unconstrained multibody model, it will result in an undesired drift of the model due to a mismatch in the mass and inertial properties between the real vehicle and its model. This is even more important when measured forces are applied to a new vehicle model that is only similar to the tested one. The TWR approach relies on a linearized model of the vehicle that is derived directly from its multibody representation. Then the spindle displacements are back-calculated by pseudo-inversion of the Frequency Response Function of the system and the application of the desired target signals. This method gives a direct result only if the system is linear; this is typically not the case in the field of vehicle dynamics where the geometry of the suspension, the non-linear properties of the dampers and bushings together with the intrinsic non-linear nature of the constrained equation of motion implies that the linearized model used by TWR is valid only for small changes to the configuration at the instant of linearization. To cope with this problem, the TWR sets up an iterative process that uses the output error to update the input. In case of high non-linearities or large changes in the configuration the linearized model can be also updated. In this paper the integration of the TWR process in a multibody code such as LMS Virtual.Lab Motion is described. In particular a new tool named LMS Motion-TWR has been developed. The application guides the engineer in setting up the models inputs and outputs, allows to drive the multibody code to compute the linearized model and the association between the test data and the numerical responses of the model. The computation of the driving signals is performed by TWR core solver as a background process allowing the user to focus on the analysis of the results rather than spending time in dealing with file conversion and transfer from one software to another as was done in the past. Moreover several post-processing tools are available such as time and frequency domain plots, RMS error and X-Y plots. Finally this paper describes the application of the tool in an industrial case scenario using a model of a quad. A quad was equipped with several sensors and driven on a test track. The collected data is then used in the Motion TWR software to compute the equivalent spindle displacements. Since some of the front suspension parts are modeled as flexible bodies the reverse load identification analysis is completed by a durability calculation.

Abstract (sommario):

Abstract Vehicle dynamics are well understood by both academic researchers and automotive industries. And while modeling and simulation tools are still underutilized, they are becoming more frequently used in the vehicle design process. However, there is still lacking an overall design methodology that can link and integrate in a systematic fashion the design tasks of individual components or systems such that the vehicle performs as intended with a minimal number of design iterations. A process called Target Cascading, applied in the early stages of vehicle design, might serve as this systematic design methodology. In this paper, Target Cascading is evaluated for its ability to propagate top-level design specifications down to specifications for various subsystems and components in a vehicle design problem. More specifically, general ride and handling targets are set for a vehicle and these are cascaded down through the suspension, tire pressure and spring design levels by partitioning the original problem into a hierarchical set of subproblems. At a given level, an optimization problem is formulated to minimize deviations from the proposed targets and thus achieve intersystem compatibility. A coordination strategy links all subproblem decisions so that the overall supersystem performance targets are met. Results are presented that demonstrate Target Cascading’s utility in unearthing tradeoffs and incompatibilities among initial targets early in the vehicle development cycle. Throughout the paper, the Target Cascading process is compared to traditional vehicle design strategies for achieving ride and handling targets. Target Cascading appears to be a promising systematic technique for the design of vehicles to meet ride and handling specifications.

Abstract (sommario):

"In research and development, the use of model-based methods has been established widely. In spite of the required costs and time for modelling and parameterization, the models become applicable in many steps of the design process from concept studies until parameter optimization. Particularly, during the early phase of the development of products or functions, it is necessary to keep time and cost efforts as low as possible without significantly reducing the quality of the simulation results. For the development of vehicle dynamic controls, the quality of the used models depends highly on the modelling of the wheel-road contact. Due to the reduced parameterization and calculation effort, mathematical-empirical or semi-physical approaches as well as flexible belt-ring models are preferred to simulate severe driving manoeuvres such as full braking with ABS intervention or the ISO 3888 double lane-change. The determination of the model parameters is carried out using special tire test rigs in which the tire and rim are clamped. Due to the complex experimental setup and the required infrastructure, these tests are very cost-intensive. In driving tests with real vehicle, commercially available wheel force transducers are used today. By means of force measuring elements, which are usually attached to an especially manufactured and split rim body, the transmitted forces and moments are determined while driving. A high-resolution angle sensor detects the rotation angle and the angular velocity of the wheel in order to transform the measured quantities (forces and torque at the wheel) from the rotating to the vehicle related coordinate system. At the beginning of the paper, established concepts of tire test rigs for determining the parameters of mathematical-empirical tire models will be summarized and compared with the proposed usage of a wheel force transducer in real-driving tests. This will include an estimation of the boundary conditions and the reproducibility of the measurements as well as influencing factors on the force transmission. Subsequently, the test equipment and driving manoeuvres that were carried out with the test vehicle are presented. In addition to the wheel force transducer, a 2-axis optical speed sensor is added to the test setup. Using the measured vehicle velocity and the measured wheel speed the tire slip can be calculated now. The measurement data is partly used for parameter identification of two simplified tire models according to PACEJKA and BURCKHARDT, which describe the steady-state friction coefficient slip characteristic. Since these are nonlinear tire models, a non-linear least squares algorithm is used as the mathematical optimization method. The measurement data, which was not used for the parameterization, are applied in the subsequent validation of the tire model. On the basis of the obtained results a statement about the usability of a parameterized tire model based on measurements with a wheel force transducer is made and possible extensions and suggestions for improvement are derived."

Abstract (sommario):

The US Army Corps of Engineers’s (USACE) Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) rainfall-runoff model is widely used within the research community to develop both event-based and continuous rainfall-runoff models. The soil moisture accounting (SMA) algorithm is commonly used for long-term simulations. Depending on the final model setup, 12 to 18 parameters are needed to characterize the modeled watershed’s canopy, surface, soil, and routing processes, all of which are potential calibration parameters. HEC-HMS includes optimization tools to facilitate model calibration, but only initial conditions (ICs) can be calibrated when using the gridded SMA algorithm. Calibrating a continuous SMA HEC-HMS model is an iterative process that can require hundreds of simulations, a time intensive process requiring automation. HEC-HMS is written in Java and is predominantly run through a graphical user interface (GUI). As such, conducting a long-term gridded SMA calibration is infeasible using the GUI. USACE Construction Engineering Research Laboratory (CERL) has written a workflow that utilizes the existing Jython application programming interface (API) to batch run HEC-HMS simulations with Python. The workflow allows for gridded SMA HEC-HMS model sensitivity and calibration analyses to be conducted in a timely manner.

Abstract (sommario):

In 2012-14 Unitec Institute of Technology (in partnership with The Innovation Workshop) carried out research into the application process for New Zealand Government Research & Development [R&D] co-funding administered by the Ministry of Science & Innovation (now Callaghan Innovation Ltd). This research revealed widespread applicant frustration with the application criteria and process. A significant problem perceived by High Value Manufacturing and Service Small Medium Enterprises (HVMS SME) businesses is the focus of R&D funding on product innovation followed by a lack of funding to support later stage commercialisation of products. This later stage of product and market development is excluded from Callaghan Innovation co-funding, leading to ‘prototypes-on-a-shelf’. Applicants also found the process time consuming, due to the complexity of the application questions and the delays in response from the funding network of regional funding partners and the Government Ministry. HVMS SME often used consultants to help manage the application, which is frowned upon by both the regional funding partners and Callaghan Innovation, despite the high levels of co-funding success from these applicants. This work has been carried out during the establishment period of Callaghan Innovation Ltd and some of the above issues may be historic and/or transitional as the institutional arrangements change. This research records the HVMS SME experience in applying for R&D co-funding. Consideration of the user experience, captured in this research, may reveal opportunities to improve the process with better outcomes for the applicants and the economy.

Abstract (sommario):

Based on literature review it was established that the use of augmented reality as an innovative technology of student training occurs in following directions: 3D image rendering; recognition and marking of real objects; interaction of a virtual object with a person in real time. The main advantages of using AR and VR in the educational process are highlighted: clarity, ability to simulate processes and phenomena, integration of educational disciplines, building an open education system, increasing motivation for learning, etc. It has been found that in the field of physical process modelling the Proteus Physics Laboratory is a popular example of augmented reality. Using the Proteus environment allows to visualize the functioning of the functional nodes of the computing system at the micro level. This is especially important for programming systems with limited resources, such as microcontrollers in the process of training future IT professionals. Experiment took place at Borys Grinchenko Kyiv University and Sumy State Pedagogical University named after A. S. Makarenko with students majoring in Computer Science (field of knowledge is Secondary Education (Informatics)). It was found that computer modelling has a positive effect on mastering the basics of microelectronics. The ways of further scientific researches for grounding, development and experimental verification of forms, methods and augmented reality, and can be used in the professional training of future IT specialists are outlined in the article.

Abstract (sommario):

The article is dedicated to the investigation of time-space measurements of journalistic works of Eugen Sverstiuk, a well-known Ukrainian journalist. In particular, the time-space continuum of his works is being discussed, which is characterized as comprehensive, continuous, filled with archetypical images which metaphorize the text, but at the same time structure it, and are beaded on the axis of time and documentarily located in the space. The logics of images initiated in the text is exaggerated by constant dwelling of the author in the time-space dimensions of the epoque, of which he was a contemporary, as well as precise knowledge of World and Ukrainian history and culture. Historical parallelism of journalism of E. Sverstiuk possesses double potential. On the one hand, the author provides arguments for confirmation of his own opinion, and on the other, he shows us historical collisions in the new aspect, which helps consider the past, better understand the present, and think of the future. Pages of his works is space for author’s considerations, which logics impresses by free transgression of the author in the time, and his ability to grasp the most essential, although sometimes precedent, sometimes sudden and forgotten, or even unknown historical facts in order to force them to resonate in the new historical realities, first of all to indicate the importance of national and the need for assigning to it more significance. Using retrospectives, E. Sverstiuk encourages us to return to the national sources and to seek in ourselves the reflections of nationality in order to return historical truth to our audience. This is what, according to E. Sverstiuk, was believed to be one of the most necessary conditions of existence to the independent state. Time-space continuum of E. Sverstiuk’s journalism is reproduction of comprehensive history as continuous process of the development of humanity, and of formation of comprehensive, total, and so to say epic reading and understanding of these processes via accentuation of reader’s attention on key events, phenomena, and facts.

Abstract (sommario):

The need to control the risk that accompanies businesses in their day- to-day operations, and at the same time changing economic conditions make risk management an almost indispensable element of economic life. Selection of the main aspects of the selected phases of the risk management process: risk identification and risk assessment are related to their direct relationship with the subject matter (risk identification to be managed; risk analysis leading to the establishment of a risk hierarchy, and, consequently, the definition of risk control’ methods) and its purpose (bringing the risk to acceptable level). It is impossible to identify the basic patterns of development of the oil and gas industry without exploring the relationship between economic processes and enterprise risks. The latter are subject to simulation, and based on models it is possible to determine with certain probability whether there have been qualitative and quantitative changes in the processes, in their mutual influence on each other, etc. The work is devoted to exploring the possibilities of applying the Granger test to examine the causal relationship between the risks and obligations of oil and gas companies. The analysis is based on statistical tests and the use of linear regression models.
