摘要
以HSV型高速开关数字阀为研究对象,为掌握该阀工作原理及工作特性,通过机理建模方法对该阀进行建模,并运用MATLAB/Simulink软件对该阀进行了仿真分析。对该阀静动态特性进行了研究,分析了影响该阀开启/关闭响应时间、饱和区和死区大小、输出流量大小的因素,并在高速开关数字阀特性测试平台上进行实验研究。最后对仿真数据以及实验数据进行比较分析,结果表明了高速开关数字阀的静动态特性分析结论的正确性。
HSV series high-speed on-off digital valves were studied herein.In order to fully understand working performances and working principles of the valves,a mathematical model was built through mechanism modeling method.By MATLAB/Simulink,a simulation model was proposed and established.Based on this model,static and dynamic characteristics of the valves were analyzed.Thus,influence factors of opening/closing response times,valve's output flows,dead and saturated zones were analyzed.At last,static and dynamic characteristics mentioned above were verified by experiments.Experimental results show that the conclusions of static and dynamic characteristic analyses for the high-speed on-off digital valves are correct.
