摘      要：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 *** 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 *** 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 *** the simulation analysis for accelerated process of the typical four-wheel-drive vehicle,the effectiveness of this method is verified.
