A New Dynamic Multi-D.O.F. Tire-Model

Abstract A new dynamic model of the generation of shear forces by pneumatic tires for all speed is proposed. This model is suitable for a wide range of applications from the study of steering performance of vehicle at low speed to realism enhancement for interactive vehicle simulator. The elastic deformation of the belt with respect to the rim is takeninto account, along with the elasto-plastic behavior of rubber-road contact in the contact patch. The model reproduce tire behaviors like frictional vertical torque at standstill, lateral force and vertical torque due to yaw speed, and also relaxation length behavior. Moreover, as the “Pacejka Magic Formula”, it represents very well the standard stationary friction curves.
