摘　　要：针对电拖动闭式液压传动系统功率匹配方法、控制技术及状态监测与故障诊断方法的研究需求,基于系统的机电液耦合特性,确定选用电、机械、液压信号传感器以及液压加载方式实验台设计方案,并进行了相应的参数设计和元件选型。在此基础上进行了实验台液压系统的仿真研究,结果表明,所设计的实验台能满足相应的设计要求。In order to research the power matching, control technique, condition monitoring and fault diagnosis of electric drive closed-loop hydraulic system, the test rig was designed by adopting mechanical-electrical-hydraulic sensors and hydraulic loading system based on the mechanical-electrical-hydraulic coupling characteristics. Meanwhile, the parameters of components were designed, based on which the simulation of hydraulic system was carried out. The results of simulation show that the test rig meets the design requirements.
