Résumé / Abstract
A numerical model for the contact between a wheel-air-tire system and a road surface is presented. The forces calculated at the center of wheel are to be used in a full numerical model of a vehicle for the in-vehicle noise prediction. The tire/road contact modeling is a difficult task because of the complex structure of the tire and the roughness of the road surface. Two numerical approaches are compared to each other in the present study: the first one solves directly the dynamic equation and the second one uses the static contact force to calculate the vibration of the tire. The numerical results of the forces at the wheel center have been compared to those of measurements conducted by PSA Peugeot Citroën. The comparison shows good agreement in the low frequency range up to 230Hz.
