METHOD FOR SIMULATING THE THERMO-MECHANICAL BEHAVIOR OF A TIRE, AND APPLICATION

摘要

The invention relates to a method for simulating the behavior of a tire fitted to a vehicle in a rolling situation on the ground, this method comprising a mechanical model making it possible to calculate in particular the longitudinal (Fx) and transverse (Fy) forces transmitted by the tire between the ground and the vehicle, according to dynamic parameters related to the physical conditions of rolling and use of the tire, and according to specific physical parameters of the tire.According to the invention, the mechanical model is coupled to a thermal model taking into account the influence of temperature on the coefficient of adhesion, and a global thermal model taking into account the influence of temperature on the shear modulus of the tire rubber.Application to the simulation of the dynamic behavior of a vehicle.
