Abstract:
The computer simulation method is used to study the crashworthiness of car bumper system. Firstly, the CAD model of the car and bumper system is established in CATIA. The pre-processing for the model is finished in Hyper-Mesh and the finite element model is established. Then the process of crash simulation is calculated in Pam-Crash. The simulation results are compared with the test results to verify the accuracy of the finite element model. Finally, the low-speed crash simulation of the bumper system is conducted. The crash displacement and deformation of the bumper system are forecast through the process of simulation, which can provide a reference for the next design and improvement.

Abstract:
We performed numerical analyses using an explicit code to evaluate the cumulative impact damage of an automotive aluminum front-end bumper back beam during low-speed crash events, as described by CMVSS215. we used a coupled numerical analysis scheme and considered the several fracture criterion such as EWK rupture model and plastic strain limit in the PAM-CRASH code to improve our damage and fracture estimates. Tensile test experiments for the notched and un-notched specimens were conducted to tune the performance of the EWK rupture model; The resulting material properties and fracture criterion were incorporated into the numerical analyses of the low-speed crash events. The simulation results were compared with the impact test.

Abstract:
Frontal vehicle structure is of high importance through crash energy managements and crash boxes are the fundamental structural component for vehicle safety as well as after sales issues. Similar to many other vehicle components, the detail design of crash box is usually part of manufacture knowhow. However, some guide lines are always available. In this article a general procedure is introduced for designing of crash box with the aid of novel thin walled structures and according to conventional crash scenarios. The problem is followed through some basic steps. Firstly, the crash box idea is selected through a wide range of previous investigated elements and is packaged in a real bench vehicle. Then thanks to the protection provided by the new crash box on the other more expensive components (e.g. headlamp, cooling pack, etc.), the effectiveness of this element are acknowledged through the low speed offset crash. Further on the robustness of new proposed crash box is approved by high speed crash simulations. The quasi-static simulations implemented during the analyses are carried out by finite element explicit code (Abaqus) and the FE modeling and dynamic simulation through the next steps are also performed in ANSA and PAM CRASH respectively. Finally in addition to the general crash box design proposed procedure, the achieved results demonstrated that the corrugated conical thin walled tubes deforms in regular and rather stable shape under both axial and oblique loadings. They also produced a reasonable reaction force versus deformations which leads to stiff and crashworthy energy absorber in comparison to traditional rectangular and even some special models like as origami shapes, and so they could be a valuable selection for crash box implementations in passenger cars.

Abstract:
Based on the European New Car Assessment Program, which offers rigorous testing conditions, this study developed a numerical model for the computer simulation of crash analysis and analyzed two crash situations: a high-speed vehicle crashing into a wall and a high-speed test vehicle crashing into a static vehicle. The Simulation model was constructed using the superior functions of the Patran software, and the Pam-crash software was employed to perform various calculations for analysis. In crashes, the structure of vehicle bodies are greatly compressed and deformed because of high-speed impact force, which simultaneously generates high speed acceleration. Vehicle structural deformation constricts the driver and passengers, and acceleration can cause them physical harm. Thus, the objective of this study was to identify the sources of harm to driver and passengers when crashes occur. The research results can be a reference for vehicle manufacturers in future vehicle development and a reference for future academic research.

Abstract:
A side impact simulation model for a car was built according to China New Car Assessment Programme(CNCAP) and the 120ms response of the side impact was calculated by Pam-Crash software. The side security performance of base model was evaluated with the assessment criteria for the side security which was defined base on the experience and development requirement. Because of the stiffness insufficiency of base model, the body side structure was improved by multiple optimizations to improve the side security performance of body-in-white. The optimal scheme was validated by the test results, and the side security performance satisfies the production development requirements. The reliability and accuracy of the side impact model were validated according to the comparison analysis of test and simulation.

Abstract:
Equal Channel Angular Pressing (ECAP) is currently being widely investigated because of its potential to produce ultra-fine grained microstructures in metals and alloys. The objective of this work is to study the effect of ECAP on Al 6061 alloy. ECAP is processed using die channel angles of 90º, 120º and 140º. The stress and the deformation behavior of the ECAP processed material were investigated by hardness tests. The finite element analysis (FEA) is carried out for ECAP using PAM-CRASH software for different channel angles, which are prescribed in the experiment. The inputs such as material properties, loads, boundary conditions, contacts and controls were provided to the software and the results were visualized. The Von Mises Stress values obtained by FEA were found to be in good consistence with the experimental stress values.

Abstract:
Negli ultimi anni nel mondo dell’industria automobilistica e aeronautica sta prendendo sempre più piede l’utilizzo di strutture assorbitrici realizzate in materiali compositi; questi materiali, infatti, oltre a possedere proprietà paragonabili a quelle dei metalli, coniugate ad un’importante riduzione della massa, possono essere modellati in modo da assorbire una notevole quantità di energia cinetica in caso di impatto. Viste le notevoli variabili presenti in fase di progettazione e i diversi metodi di rottura con cui questi materiali possono collassare, risulta fondamentale l’utilizzo di simulazioni che riescano a prevedere con precisione il loro comportamento. In questo progetto di tesi viene proposta un’analisi bibliografica degli articoli che affrontano questo studio con il software ad elementi finiti PAM-CRASH, analizzandone la metodologia e gli accorgimenti utilizzati. In tal modo è stato possibile esaminare i differenti modelli di danno adoperati nel corso degli anni, individuandone i punti di forza e le mancanze, stilando delle linee guida per il loro utilizzo pratico.

Abstract:
L’obbiettivo di questo lavoro di tesi è analizzare le performance a crashworthiness di provini sinusoidali autoportanti, realizzati in tessuto plain weave (fibra di carbonio, intrecciata in trama e ordito, e matrice polimerica). La tesi si articolerà essenzialmente in due parti. La prima riguarda una campagna sperimentale (presso il laboratorio strutture MasterLab della Seconda Scuola di Ingegneria dell’Università di Bologna, con sede a Forlì) effettuata su provini di dimensioni specifiche, secondo normativa ASTM, per l’identificazione delle caratteristiche meccaniche del composito, con successiva prova di schiacciamento di due tipologie di provini ondulati autoportanti, aventi stratifiche differenti, i cui risultati saranno utilizzati come valori di riferimento per la convalida dei modelli numerici. La seconda parte comprende le simulazioni numeriche, elaborate secondo il modello di danno di Johnson, Pickett, Rozycki, per la lamina costituita da tessuto, ed il modello di Pickett per l’interfaccia di delaminazione.

Abstract:
Abstract Dynamic simulation solver codes are now extensively used by industry for the design verification of vehicle crashworthiness and for the process simulation of sheet metal forming. The logical next step is to use these by now proven codes for the optimization of the vehicle crash design and of metal forming processes. A step towards this goal has been taken by PSI, and an optimization code, PAM-OPT™, has been written for calling dynamic FE codes of the PAM-SOLID™ family in design and process optimization loops. The code interacts with the user via input, signalling and output files and it calls an interface that interacts with the FE solvers. The paper briefly outlines the properties and various flow charts of the optimizer, depending on single or multiple solvers used in the loop, single or parallel calls and fast solvers. Then the paper reports various applications of PAM-OPT™ in conjunction with the PAM-SFE™, PAM-CRASH™, PAM-SAFE™ and PAM-STAMP™ solvers. An outlook on how to replace the user-written interface with a general keyword-driven interface concludes the paper.

Abstract:
The rapid progression of computational power and development of non-mesh particle modeling techniques provides solutions to problems which are not accurately modeled using traditional finite element analysis techniques. The field of soft soil modeling has been pressing on in recent years and the smoothed particle hydrodynamics (SPH) modeling method in PAM-CRASH provides opportunity for further advancement in accuracy. This research focuses on the development of soft soil models using SPH with verification using pressure-sinkage and shear strength criterion. Soil model parameters such as geometry and contact model are varied to determine the effect of the parameters on the behaviour of the soft soil and relationships are developed. The developed virtual soil models are compared against existing soils to determine which soils are accurately modeled and further refinements are made to validate the models with existing empirical data.

Abstract:
The BOSS Quattro system (developed by Samtech s.a.) is an open architecture allowing to run various optimisation engines including gradient based methods (SQP, GCMMA, Conlin, MDAQ, ...), DOE and Response Surfaces, and Genetic Algorithms. This system has been used and various optimisation strategies compared for the resolution of non linear optimisation problems including crash worthiness and airbags opening simulation. Thanks to BOSS Quattro open architecture, using neutral or specific drivers so to read information from models, software like MADIMO, Pam Crash, LS-Dyna, but also NASTRAN, SAMCEF and Abaqus can been used in order to model the non linear behaviour of the optimised vehicles. One or several models were used and computation distributed by BOSS parallel architecture on network of workstations. Direct parallel mode can be used, or the tasks distributed on the network through a Task Manager like for example LSF. As a first example, the optimisation of a stiffened box is performed using one (dynamic) then two models (static but elasto-plastic/dynamic). The external software used are NASTRAN and ABAQUS. A second example deals with the optimisation of a Golf crash model using MADIMO to represent a sequence of events including opening of air bags. Mixed optimisation is performed using as design variables : the time to open a given airbag (continuous) or the type of wheel configuration (pure discrete variable). Constraints are related to safety of the passenger (sternum invasion, various criteria related to accelerations).

Abstract:
Constraints on the safety of nuclear power plant components have increased recently along with the necessity to extend the lifespan of existing plants. For example, the acceleration levels to be sustained by the plant equipment during an earthquake have been increased many folds by the safety regulation agencies. Industrial and economic requirements plead for a verification of unknown safety margins, by accurate and physics based models taking into account all non-linear effects (for example contacts and fluid structure interaction). These effects are only approximately represented by standard linear analysis tools. Virtual Performance Solution (VPS), developed by ESI Group, includes (among other capabilities) a structural finite element software for non-linear, high velocity, dynamic simulations (PAM-CRASH), as well as a coupled, mesh free CFD module, FPM (Finite Point Method), developed in partnership with Fraunhofer ITWM. This solution accurately predicts fluid structure interactions, taking into account non-linear structural effects (contacts, friction, damping…) as well as complex fluid influences.
