为了探讨油气悬挂系统连通方式与整车操纵稳定性和行驶平顺性的关系,针对三轴车辆油气悬挂系统的6种连通方式进行研究。在双气室油气悬挂系统仿真分析和实验验证的基础上,利用ADAMS和AMESim建立各种不同连通方式的油气悬挂系统整车联合仿真模型,主要讨论了各连通方式的油气悬挂系统垂直、侧倾以及俯仰的刚度和阻尼特性。仿真研究结果表明,各连通形式中L3型油气悬挂系统综合特性更好。

英文摘要：

To discuss the relationship between interconnected modes of hydro-pneumatic suspension and multi-axle vehicle handling stability,riding comfort,6 interconnected modes of hydro-pneumatic suspension of a3-axle vehicle were studied. Based on the results from the simulation and the experiments of a double chamber hydro-pneumatic suspension system,the co-simulation models of the vehicle with different interconnected modes of hydro-pneumatic suspension were set up by ADAMS and AMESim software. Furthermore,the vertical,rolling and pitch stiffness and damping characteristics of every suspension system were given. The simulation results showed that interconnected mode L3 of a hydro-pneumatic suspension system has better comprehensive performance.
