Résumé / Abstract
Tire/road contact is the principal source of car noise at speeds greater than 50 km/h. In this context, we have developed a new approach for modelling the tire vibrations and the contact with the rigid road surfaces during rolling. For the tire, a periodic model is used to compute Green’s functions. The response of the tire can thus be modelled over a large frequency range. Then a fast convolution and contact model is developed and examples of computations of contact forces are given for real road textures. Spectra of forces for different tire velocities areal so computed.
