先导式减压阀在中高压气液动系统中得到广泛应用,由于其静态和动态特性对整个回路的工作状态有明显影响,因此,需对减压阀的工作特性进行研究。针对典型结构的先导式减压阀,建立其数学模型和仿真模型,根据仿真结果对其输出压力、流量等静态和动态特性进行分析,可对减压阀的工作状态和内部机制有更深刻的理解。仿真结果表明:利用AMESim进行仿真具有建模简便、模型精确、运算快捷的优点,能够有效节省试验和设计成本。
先導式減壓閥在中高壓氣液動繫統中得到廣汎應用,由于其靜態和動態特性對整箇迴路的工作狀態有明顯影響,因此,需對減壓閥的工作特性進行研究。針對典型結構的先導式減壓閥,建立其數學模型和倣真模型,根據倣真結果對其輸齣壓力、流量等靜態和動態特性進行分析,可對減壓閥的工作狀態和內部機製有更深刻的理解。倣真結果錶明:利用AMESim進行倣真具有建模簡便、模型精確、運算快捷的優點,能夠有效節省試驗和設計成本。

The pilot type pressure reducing valve is widely used in the high pressure pneumatic and hydraulic systems.Due to its static and dynamic characteristics have a significant effect on the working condition of the entire loop,the work characteristics of pres-sure reducing valve should be analyzed.For a pilot type pressure reducing valve with typical structure,its mathematical model and sim-ulation model were established;based on the simulation results,the output pressure and flow rate and other static and dynamic charac-teristics were analyzed,so the working status and internal mechanism of pressure reducing valve could be understood better.It is shown the AMESim simulation has such advantages of simple modeling,accurate model,fast operation,lower test and design cost.
