摘　　要：以工程机械液压系统性能试验台的转向系统为物理模型,通过试验研究液压泵的动态性能。根据试验结果,得出油箱位置、变频电机转速、加载电压等系统工况对液压泵动态性能的影响,同时得出液压泵压力、流量的动态变化对液压系统的影响。Taking the steering system of the construction machinery hydraulic system performance testing platform as physical model, the dynamic performances of the hydraulic pump were studied by local experiments. According to the test results, the influ- ences of motor speed, fuel tank position, load voltage on the hydraulic pump performance as well as the effect of hydraulic pump pres- sure and flow change to the hydraulic system were obtained.
