“…It appears that finite element modelling can help designers achieve a better understanding of the behaviour of roadside safety structures and the vehicle involved and hence improve the crashworthiness of the energy absorber in question. Various authors [78,79,80,81] have used the explicit version of the FE code to analyse various types of road side barriers and their interaction with the impinging vehicle.…”

“…But it's one of their objectives. The exploration of co mputational methods in crashworthiness applications are involved in recent works dealing with vehicle impact nu merical simulat ion, or dynamic biomechanical simu lations [20][21][22][23]. Principles of nu merical computations are the same fo r all these topics.…”

This paper focuses on industrial design and crash simulation. Indeed, crash simulation has progressed considerably to become a key area in product design, especially in auto motive industry. The main object ive of this paper is to show the role of the numerical simu lation on the design process and to explain its integration in this process. Actually, we can now talk about a strong connection between the simulation and the design process. It allows significant gains, however it highlights the problem of co llaboration around knowledge in the design process. Indeed, each expert model is driven by specific data which are shared by several users and used at the same time in a concurrent engineering context. Thus in this paper, we propose at first an assess of differents kind of crash simulation integration on design process and their benefits/limits. Then we propose an approach referred to as KCM -Knowledge Configuration Management, based on management of fine granularity knowledge in configuration. This approach is likely to imp rove collaboration between project participants, improving capitalization, traceability, reuse and consistency of the knowledge used simultaneously on several activities in parallel within the design process. Finally, the purpose of our paper is to find new ways to further optimize the simu lation/Design integration through an approach of knowledge management which is a new challenge today in industry.

“…Computer simulations have become a practical alternative to full-scale crash tests for crashworthiness analysis of different crash scenarios [22][23][24][25][26][27] . In addition to applications in vehicular crashworthiness design, crash simulations are also used for evaluating the safety performance of highway safety hardware [28][29][30][31][32][33][34][35][36][37][38][39][40][41] . The use of simulations has progressed from retroactively modeling crash tests to proactively supporting hardware design decisions and providing guidance for roadside hardware installations and placement.…”
