Optimization Of Structural Dynamics With A Full Vehicle Model

The finite element full vehicle model is a dynamic, multi-purpose model designed for analysis purposes. With it's aid most structural dynamic problems can be dealt with. It is possible to simulate the effect of harmonic engine excitation, stochastic excitation, e.g. driving on rough roads and extreme loading, e.g. a wheel hitting the kerb. With the finite element full vehicle model individual vehicle components can be designed and vehicle concepts assessed in terms of ride comfort. This is not only done prior to producing the first prototype but also in parallel with development, in order to continuously support design and testing. To be able to fulfil this task additional development efforts have been undertaken within the NASTRAN finite element environment. These include models to handle important physical effects, refined meshing in critical areas and additional graphic assessment possibilities.
