| Abstract: | The structure of hydro-pneumatic spring of heavy vehicle was introduced.The mathematical models of the nonlinear damping and single-wheel two DOF vibration were built for the hydro-pneumatic suspension system.On this basis,the two DOF vibration simulation model of single-wheel hydro-pneumatic suspension system was built with AMESim.The influences of changing the orifice area of damping on the body of vehicle were analyzed.The results show that the orifice area has a great influence on vibration attenuation ... |
