Driving performance of off-road vehicle matching with tire by simulation

The dynamic performance of the integrated system matched by the tire and the vehicle are the main factors for the driving performance of the vehicle. In order to improve the accuracy of simulation on driving performance of off-road vehicle and match correctly between the tire and the vehicle, the finite element method was used to establish model of radial tire and analysis the characteristics of tire in driving state, and the brush model of the tire are introduced contrastively. The dynamics models of the off-road vehicle which provide an off-line dynamic simulation for driving performance of the vehicle are investigated in the MATLAB/Simulink environment. The driving performance of the vehicle selected previously is investigated experimentally. There is an excellent agreement between the numerical and the experimental results.
