摘　　要：构建压力-流量控制系统,介绍压力-流量控制系统的调节原理。利用AMESim软件建立压力-流量控制系统的仿真模型,分析恒压阀阀芯面积、阀芯质量对恒压阀动态性能的影响。仿真结果表明:恒压阀阀芯面积和阀芯质量对恒压阀动态性能有着重要的影响,应根据具体要求合理选择。Pressure-flow control system was established and regulating principle of the system was introduced. The simulation model of the system was established by using AMESim software. The impacts of area and weight of constant pressure valve spool on its dynamic characteristics were simulated. Simulation resutts show that the area and weight of constant pressure valve spool have an important impact on the dynamic characteristics of constant pressure valve. They should be chosen rationally according to requirements.
