Abstract:
AbstractThe Integrated Logistics Support (ILS) can be described as an approach for optimisation of in-service (logistics) activities and minimisation of the life cycle costs of a system. ILS is an integral part of systems engineering in aerospace and defence programmes.More recently, the Aerospace and Defence Industries Association of Europe (ASD) has released a broad set of specifications for ILS, the so-called ASD ILS Suite. Most of these specifications are published in cooperation with the Aerospace Industries Association of America (AIA) and one specification with AIA and the Airlines for America (A4A). Thus, the ASD ILS Suite is recognised and used in the largest aerospace and defence markets.The aim of this paper is to present the results of a critical review on the readiness of the ASD ILS Suite for its applicability in aerospace and defence programmes.

Abstract:
Economists since Adam Smith have recognized the contribution of innovation to profitability and growth. The relationship between corporate research and development and subsequent sales growth, both across and within industries, has been examined by many authors. Results have been varied showing at best no more than the suggestion of a causal relationship between research and development input and growth. These results are reviewed together with the various theories which have been developed in an attempt to explain the connection between technical innovation and growth. Starting with an examination of various national economies, the rate of commercial research and development expenditure has been compared to the rate of national growth. A number of industries in the United Kingdom, Germany, Japan and the United States of America were also examined, taking the automotive industry as a particular case. In addition to using published data a survey of smaller vehicle manufacturers in the United Kingdom was conducted. Although positive correlation was found at an international and industry level, no association between research and development expenditure and sales growth was found at a company or project level in the United Kingdom.

Abstract:
In today's world, most industries use service quality in a variety of fields. The five service quality characteristics are tangible, assurance, reliability, responsiveness, and empathy, and they are being implemented across all industries. The primary goal of this study is to look into the quality of service provided by hospitals in North America and how that affects patients’ satisfaction. Furthermore, to determine which service quality factor has a greater impact than the others. The association between each service quality factor and visitor satisfaction was measured using a quantitative research method by the researcher. Patients in North America's hospitals were given a questionnaire that had been developed and circulated. In North America, 111 questionnaires were completed and received from hospitals patients. The findings revealed that the highest value was assigned to responsiveness as a service dimension, while the lowest value was assigned to assurance as a service dimension.

Abstract:
Serious students of popular music and song are rightly curious about the workings of the music business; but when we try to find out about how the industry works, even in terms of economics, we find that virtually all the empirical data comes from internal sources, from the International Federation of Phonographic Industries (IFPI), or from affiliates such as the British Phonographic Industries (BPI) and the Recording Industry Association of America (RIAA). In other words, we get only those statistics and ‘facts’ which this most secretive of industries wishes us to have; so we will look in vain for detailed production figures, or for sales of individual recordings (unless they are outstandingly successful), or for hard numbers relating to what IFPI calls ‘piracy’ (let alone the information on which the published numbers and projections are based). Similarly, from the individual company accounts of Sony, EMI or BMG, we may find numbers relating to pension and investment funds, but we will never find the real profits or losses of any company, let alone the rate of exploitation of any artist (or manufacturing or distributive worker); and in any case it is well-known that the published ‘bottom-line’ on a balance sheet is, at best, an informed opinion.

Abstract:
Abstract Composites are being used in the place of metals in many industries as they have a lower density and are cheaper than metals. In aerospace industries there is requirement for light weight together with strength, and reinforced fibre composites are superior in some critical properties compared with metals. In this study, laminated composites were fabricated with woven E-glass and jute fibres in an epoxy matrix by a hand layup method. The samples were prepared as per the relevant the America Society for Testing ad Materials (ASTM) standard and tested for mode II interlaminar fracture toughness to investigate delamination resistance. Mode II interlaminar fracture toughness was evaluated by an end-notched flexure test using three-point bending. The fracture toughness G IIC was calculated for a curing temperature range from 40 °C to 70 °C at intervals of 5 °C for different sets of laminated composites. The investigations revealed that when the curing temperature of laminated composites was increased from 40 °C to 70 °C, the interlaminar fracture toughness G IIC was increased in neat woven E-glass laminated composites, decreased in neat jute laminated composites, significantly increased in laminated composites with woven E-glass fibres in compression and jute fibres in tension and slightly increased when woven E-glass fibres were kept in tension and jute fibres in compression.

Full text
Abstract:
This paper identifies and explores possible safety implications of RoHS (Restriction of Hazardous Substances) compliance on railway equipment, with the purpose of presenting this topic for further consideration in North American industry standards, e.g. AREMA (American Railway Engineering and Maintenance-of-Way Association) guidelines. Of specific interest is the topic of tin whiskers, which are known to grow in electric circuits that are Lead free. Tin whiskers have the ability to bridge the gap between two vital signals in a circuit, creating the possibility for a potentially hazardous scenario to occur in a safety-critical system. As rail transportation technologies become progressively more dependent on safety critical electronics that are RoHS compliant, the subject of tin whiskers merits its due consideration in the industry. There are verified incidents of tin whiskers having adverse impact in the automotive and aerospace industries; examples are provided in the paper. If precautionary measures are not respected, it is possible that a short circuit resulting from tin whiskers may lead to an undesirable incident in the rail industry also. Research has shown that there are proven techniques which can inhibit tin whisker growth to an acceptable level. Mitigating measures and their effectiveness in deterring whisker growth are discussed in this paper. Awareness is essential in prevention of a hazard. Railroads and Transit agencies that recognize hazards posed by metal whisker growth will be in a better position to evaluate the safety of RoHS compliant products provided by system integrators, who, in turn, must account for the issues presented in this paper in their internal quality processes. In due course, the safety implications of RoHS transitioning should be considered in an industry-wide guideline such as AREMA, laying the foundation for future RoHS compliant railway equipment that is safeguarded against safety concerns from tin whisker growth.

Full text
Abstract:
The connection between bearing raceway condition and fatigue in tapered roller bearings utilized in the railroad environment is of interest. Roller bearings for railroad applications are typically precision ground to exact dimensions with crowned contact geometries for optimal loading of components. This normally results in completely elastic Hertzian contact stresses under standard railcar loads with original equipment manufacturer raceway contact geometries. However, with extremely uneven bogie load distributions, impact damage, corrosion and spall repair, imperfect stress distributions can occur on bearing raceways utilized in the railroad environment. Railroad bearing applications in North America have the added complexity that the life of the product is not defined in the same way as in other industries. For example, the definition of spalling remains consistent across all industries and is outlined in the Association of American Railroads (AAR) Manual of Standards and Recommended Practices. However, an inconsistency compared to other industries is that the fatigue life of the product in the rail industry is not always considered complete at the first evidence of fatigue spalling. Although some other industries allow for the remanufacture and restoration of bearing assemblies, the aggressive raceway fatigue regrinding practices allowed by the AAR are not commonly permissible in other industries. These remanufacturing practices adversely influence subsurface stress magnitudes below the raceway surface, as they reduce the effective length of the raceway and can create stress risers. Engineering tools like the novel modeling method presented in this paper can be used by bearing designers to evaluate the impact of surface discontinuities, at the center or edge of the raceway, on the overall stress state of bearing raceways. For the various types of raceway conditions detailed above, a new tool was developed using finite element methods to simulate the stress state of the bearing under complex raceway contact geometries or adverse load conditions. The finite element contact stress tool was successfully validated using proven Hertzian contact theory. Peak maximum shear and von Mises subsurface stress predictions between the finite element model and conventional contact theory agreed within .001 inches, with regards to peak stress depth below the surface, and 10,000 psi, with regards to peak stress magnitude. This newly developed methodology will be used in future studies to analyze other load conditions and raceway contact geometries that cannot be analyzed with basic Hertzian contact theory, in order to illustrate practical application of the tool. Specifically, overload conditions are analyzed in the work presented. Furthermore, a proposed methodology for future work related to the examination of the stress state created by current AAR bearing reconditioning acceptance standards related to raceway impact damage and spall repair will be introduced.

Abstract:
The Aerospace Industries Association (AIA) Rotor Integrity Sub-Committee (RISC) has proposed an enhanced damage tolerance design strategy for critical rotating parts intended to reduce the rate of uncontained rotor events. Building upon the industry committee’s experience in developing a probabilistic relative risk assessment methodology for hard alpha anomalies in titanium rotors, a similar probabilistic approach has been proposed for induced anomalies along machined hole surfaces in engine rotors. Key inputs to this strategy are the development of a surface anomaly distribution for machined holes and the benchmark of design target risk (DTR). The DTR is an FAA/industry agreed upon design target value of relative risk against which the results of the probabilistic risk assessment are compared.

Full text
Abstract:
Due to increasing energy costs and emissions restrictions, many industries are paying closer attention to the energy required to keep their equipment operating. Parasitic losses in power such as those due to the drag produced by contacting lip seals that are found in a variety of rotating equipment can significantly add to the total operating costs of that equipment. In mobile industries (railroad, heavy truck, and automotive), these losses can significantly affect the amount of fuel consumed and emissions produced. Power losses due to seal drag are also accompanied with frictional heat and wear which can degrade components and lead to maintenance costs to service or replace these components. To address these issues for the railroad industry, Timken has developed a non-contacting seal for use in railroad bearings. A review is given of the design and development of a non-contacting labyrinth seal for railroad bearing applications. The seal has been qualified by the Association of American Railroads (AAR) for use in North America freight car service and is currently the only non-contacting seal in operation for this market. The unique design of the labyrinth pathway allows for zero seal drag with exceptional grease retention and contaminant exclusion capabilities as compared to contacting elastomer lip seals that are typical for this industry. Experimental test performance of this seal will be compared to other seals that are currently used in this industry. Operating torque reductions of 10–30 in-lb per seal achieved through this technology can lead to fuel savings on the order of hundreds of thousands of gallons per year corresponding to the elimination of thousands of tons of emissions due to the reduced fuel usage in the U.S. alone. These savings can be passed directly to railroads and freight car owners as well as the general population with lower operating costs, increased reliability, longer service life, and reduced emissions.

Full text
Abstract:
Over the past two decades, the Federal Aviation Administration (FAA) and the aircraft engine industry (organized through the Rotor Integrity Sub-Committee (RISC) of the Aerospace Industries Association) have been developing enhanced life management methods to address the rare but significant threats posed by undetected material or manufacturing anomalies in high-energy rotating components of gas turbine engines. This collaborative effort has led to the release of several FAA advisory circulars providing guidance for the use of probabilistic damage tolerance methods as a supplement to traditional safe-life methods. The most recent such document is Advisory Circular (AC) 33.70-2 on “Damage Tolerance of Hole Features in High-Energy Turbine Rotors.” In parallel with this effort, the FAA has also been funding research and development activities to develop the technology and tools necessary to implement the new methods, including a series of grants led by Southwest Research Institute® (SwRI®). The most significant outcome of these grants is a probabilistic damage tolerance computer code called DARWIN® (Design Assessment of Reliability With INspection). DARWIN integrates finite element models and stress analysis results, fracture mechanics models, material anomaly data, probability of crack detection, and uncertain inspection schedules with a user-friendly graphical user interface (GUI) to determine the probability of fracture of a rotor disk as a function of operating cycles with and without inspection. This paper provides an overview of new DARWIN models and features that directly support implementation of the new AC on hole features. The paper also simultaneously provides an overview of the AC methodology itself. Component geometry and stresses are addressed through an interface with commercial three-dimensional finite element (FE) models, including management of multiple load steps and multiple missions. Calculations of fatigue crack growth (FCG) life employ a unique interface with the FE models, sophisticated new stress intensity factor solutions for typical crack geometries at holes, shakedown modules, a menu of common FCG equations, and algorithms to address the effects of varying temperatures on crack growth rates. The primary random variables are based on the default anomaly distributions and probability-of-detection (POD) curves provided directly in the AC. Fracture risk is computed on a per-feature basis using one of several available computational methods including importance sampling, response surface, and Monte Carlo simulation. The approach is illustrated for risk prediction of a representative gas turbine engine disk. The results can be used to gain a better understanding of the AC and how the problem is solved using the probabilistic damage tolerance framework provided in DARWIN.

Full text
Abstract:
Fifty years ago, the railcar industry relied entirely on classical analysis methods using fundamental solid mechanics theory to establish design and manufacturing protocols. While this method produced working designs, the assumptions required by this type of analysis often led to overdesigned railcars. In the 1950s, the generalized mathematical approach of Finite Element Analysis (FEA) was developed to model the structural behaviors of mechanical systems. FEA involves creating a numerical model by discretizing a continuous system into a finite system of grid divisions. Each grid division, or element, has an inherent geometric shape and each element is comprised of points which are referred to as nodes. The connected pattern of nodes and elements is called a mesh. A solver organizes the mesh into a matrix of differential equations and computes the displacements using linear algebraic operations from which strains and stresses are obtained. The rapid development of computing technology provided the catalyst to drive FEA from research into industry. FEA is currently the standard approach for improving product design cycle times that were previously achieved by trial and error. Moreover, simulation has improved design efficiency allowing for greater advances in weight, strength, and material optimization. While FEA had its roots planted in the aerospace industry, competitive market conditions have driven simulation into many other professional fields of engineering. For the last few decades, FEA has become essential to the submittal of new railcar designs for unrestricted interchange service across North America. All new railcar designs must be compliant to a list of structural requirements mandated by the Association of American Railroads (AAR), which are listed in its MSRP (Manual of Standards and Recommended Practices) in addition to recommended practices in Finite Element (FE) modeling procedures. The MSRP recognizes that these guidelines are not always feasible to completely simulate, allowing the analyst to justify situations where deviations are necessary. Benefits notwithstanding, FEA has inherent challenges. It is understood that FEA does not provide exact solutions, only approximations. While FEA can provide meaningful insight into actual physical behavior leading to shorter development times and lower costs, it can also create bogus solutions that lead to potential safety and engineering risks. Regardless of how appropriate the FEA assumptions may be, engineering judgment is required to interpret the accuracy and significance of the results. A constant balance is made between model fidelity and computational solve time. The purpose of this paper is to discuss the FEA approach to railcar analysis that is used by BNSF Logistics, LLC (BNSFL) in creating AAR compliant railcar designs. Additionally, this paper will discuss the challenges inherent to FEA using experiences from actual case studies in the railcar industry. These challenges originate from assumptions that are made for the analysis including element types, part connections, and constraint locations for the model. All FEA terminology discussed in this paper is written from the perspective of an ANSYS Mechanical user. Closing remarks will be given about where current advances in FEA technology may be able to further improve railcar industry standards.
