Towards a support system for simulation aided-design in the development phase of automotive industry

Abstract : This research aims to support the simulation-aided design process in the development phase of vehicles. The development phase is supported by modelling and simulation and consists of iteratively refining the design specifications, evaluating the vehicle's performance and solving design issues encountered. We are in a context of simulation-aided design since the decision about the vehicle design is mainly based on simulation. In this thesis research, our focus is mainly on the crash simulation analysis process. The simulation-aided design is knowledge-intensive; it depends heavily on the knowledge of analysts and experts.First, we identify the difficulties and challenges encountered in the design issue resolution process. Therefore, we conduct an empirical study to understand better the simulation-aided design process in use in the company. The industrial challenges have been identified based on a two-level analysis, the analysts' team level and the project level. The challenges include the access and share of knowledge, data consistency, and the formalisation of approaches and the process. The empirical study confirms that knowledge is a key factor for the improvement of the simulation-aided design process.Moreover, we propose an ontology to formalise crucial knowledge for car crash simulation. The ontology we have developed is called the Crash Simulation Post-Processing Ontology. This ontology formalises knowledge related to the post-processing phase of car crash simulation and the interpretation of simulation results. The aim is to formalise knowledge related to the resolution of design issues and the proposal of design changes.Furthermore, the multidisciplinary, highly collaborative and contextual nature of engineering design has raised the need to support integrated and collaborative product development. Successful collaborative engineering design depends on the ability to manage and share engineering knowledge. Therefore, nowadays, knowledge management plays a crucial role in business competitiveness, hence our proposal of an integrated and collaborative ontology-based approach to knowledge management. We develop an ontology-based knowledge management support system with a focus on knowledge retrieval. The architecture of the support system is proposed, and implementation for its evaluation is undertaken. The support-system proposed is proven effective for capturing engineering knowledge, facilitating design-issue resolution and saving analysts' time.
