摘　　要：分析了液压驱动汽车专用升降机典型液压系统,建立了通用的模块化仿真模型。通过实例研究了初始容腔体积和负载变化对液压系统动态性能的影响,得到如下结论:初始容腔体积和负载的增加都有利于减小液压系统启动瞬间的液压冲击,但对停止瞬间的动态性能产生不利影响,并使达到稳定状态的时间增加。The paper analyzes the typical hydraulic system for hydraulic - drive vehicle lift, with the universal modu- lar simulation model built. Research on effect of changes of initial vessel volume and load on dynamic property of the hy- draulic system is done through examples, which shows that increase of either initial vessel volume or load is beneficial to reduce the hydraulic impact at startup of the hydraulic system, but has adverse impact on dynamic property at shutdown moment and increases the time of reaching the stable status.
