Analysis of Front End Systems in Frontal Crash Configurations

Euromotor Course "Body Engineering" 28.-29.11.2001, Aachen

Dipl.-Ing. Thorsten Parr, Institut für Kraftfahrwesen Aachen (ika), Germany

Summary:

In the automotive development process, the requirements concerning passive safety, economy, integration and lightweight construction increase constantly. Composite structures, consisting of several materials, are suitable to fulfil these demands. Whenever these vehicle components are used for structural applications, they have to be modelled properly in crash simulations for the vehicle design process. A model for the simulation of these composite structures will be presented in the context of this lecture. A method, based on experimental and numeric procedures, will be developed to set up the model. This is done in several stages, starting off with the analysis of a single connection element, going on with a vehicle component and ending with the vehicle front end structure. The influence of the reinforcement will be assessed on this basis.
