Investigation to simulation of the vehicle ramp traction based On numerical calculation of tire

In order to improve the practicality and accuracy of simulation on vehicle traction performance, the simulation models of tire on vehicle traction performance are built by using three-dimensional finite element analysis, and on this basis the traction performance characteristics on entire vehicle are discussed. Aiming at a four-wheel-drive vehicle, the mathematical models about the accelerated process are built, the dynamic simulations are carried out in Simulink simulation environment, and a comparative analysis with the simulation results on bilinear tire model is put up. The results of the analysis show that: it can effectively reflect the vehicle actual accelerated process by the simulation analysis of vehicle traction performance in which the tire models are built by the tire numerical calculation methods. Through the simulation analysis for accelerated process of the typical four-wheel-drive vehicle, the effectiveness of this method is verified.
