摘　　要：为了测试静液压传动车辆在实际行驶工况时的疲劳特性,设计了轮边加载液压系统,利用AMEsim软件建立了试验台轮边加载系统的仿真模型,并进行了仿真分析,仿真结果表明:在低速大负载和高速低负载的情况下加载和降载的过程均比较理想,在载荷变化的过程中对液压马达的转速有一定的影响,液压马达的转速经过一段的动态过程,会重新保持到设定转速,选定的液压系统液压泵和液压马达的工作参数能满足车辆的行驶要求。In order to test the fatigue characteristics of hydrostatic transmission vehicles under actual driving conditions,a comprehensive performance test bench was designed. In order to make the designed test bench meet the test requirements of the test bench,the simulation model of the test wheel wheel loading system was established by AMEsim software. The simulation analysis shows that the loading and unloading process is ideal under the conditions of low speed and large load and high speed and low load. It has a certain influence on the rotation speed of the hydraulic motor during the load change process. After a period of dynamic process,the speed will be re-set to the set speed. The selected hydraulic system hydraulic pump and hydraulic motor can meet the driving requirements of the vehicle.
