摘　　要：介绍了电液比例溢流阀的工作原理,利用AMESim仿真软件搭建了电液比例溢流阀的模型,得到了阀的输入电流-压力曲线和压力-流量曲线,并且分析了主阀口阻尼孔直径、先导阀口阻尼孔直径、主阀芯上腔容积、先导阀入口容积以及主阀弹簧刚度等不同参数对电液比例溢流阀的动态特性的影响,从而为电液比例溢流阀结构参数的优化设计提供了条件。The working principle of electro-hydraulic proportional relief valve has been intro-duced and the model has been built by using AMESim simulation software.The input current-pressure curve and pressure-flow curve of the valve have been obtained.The orifice diameter of main valve port and pilot valve port,core cavity volume of main valve,pilot valve on the inlet volume and the main valve spring stiffness of different parameters on the dynamic characteristics of electro-hydraulic proportional relief valve have been analyzed.The results provided theoretical reference for the optimization design of the structural parameters of the valve.
