Dynamique des véhicules. Outil d'aide à la simulation des accidents routiers.

This work presents an approach for simulation of vehicle dynamics taking into account suspension and elasticity of the tyres. The model used for the wheel-ground contact is the linear model of tyre that is particularly suitable for applications in criminalistic accidentology. The use of a more complete model can extend this approach to more general applications. Mots clefs : dynamique, vehicule, simulation, accidents, derapage.
