| Abstract: | The influences of multiaxile vehicle suspension on ride comfort, operation stability of a vehicle were investigated and the system has a better performance than those of any other style for off-road vehicle. A plane model of the multiaxile vehicle was established, which was a nolinear suspension. The simulation of the dynamic responses of hydro-pneumatic suspension with changeable stiffness and dumping to a roughness terrain were performed and the results were analyzed. The results show that the hydro-pneumatic suspension can improve the ride comfort of off-road vehicle. |
