摘　　要：为了研究电液比例模拟加载系统的加载的性能,分析电液比例溢流阀加载与电液比例节流阀加载特点以及适用场合。首先分析两种阀的加载原理,然后在AMESim中建立两种加载系统的仿真模型,最后在实验台上进行实验验证。结合仿真结果与实验数据对比两种加载系统的性能特点可得:受到最小稳定流量的影响溢流阀加载适用于马达输出扭矩比较大的场合,而节流阀进出口压差较大时节流损失较大,节流加载适用于马达输出扭矩比较小的场合。在建立模拟加载系统时,同时建立溢流加载与节流加载系统,这样充分利用两种加载的优势,使得加载系统应用范围更广。In order to study the performance of the electro-hydraulic proportional simulation loading system, analysis the characteristics andapplications of the electro-hydraulic proportional relief valve loading system and electro-hydraulic proportional throttle valve loading system.Firstly, analysis loading principle of two kinds of valves, and then establish simulation model of two kinds of loading system in AMESim,and finally verify it in test-bed.Compare the characteristic of two kinds of loading system by the comparison between simulation resultsand experimental data, the result show that : subject to the minimum stable flow effects of valve, the relief valve is suitable foroccasions thatloading in the motor output torqueis relatively big, the throttle loss is big when pressure difference between import and export of throttlevalve is big, the throttle valve is suitable foroccasions that loading in the motor output torqueis relatively small, In the establishment of simulationloading system, the relief valve loading system and throttle loading system are established at the same time,which makes full use ofthe advantages of the two kinds of loading, so that the application scope of the loading system is more extensive.
