摘　　要：以国产双喷嘴挡板电液伺服阀为研究对象,推导出其数学模型。根据电液伺服阀的实际结构参数,运用Simulink仿真软件对数学模型进行仿真,得到电液伺服阀闭环阶跃的响应图和伯德图。通过改变目标参数Kvf、ωmf、ξ′mf的大小,得到不同的电液伺服阀伯德图;通过分析电液伺服阀动态性能的变化,从而达到其参数优化的目的。In this paper,a certain home-made dual nozzle flapper electro hydraulic servo valve is studied and its mathematic model is deduced.According to the actual structure parameters,with Simulink software simulation,the closed loop order servo valves step response figures and Bode figures are obtained from the simulation.By changing the main target parameter Kvf,ωmf,ξ′mf,different Bode figures are obtained.To achieve the parameter optimization of the servo valve,the alteration of the servo valve dynamic performance is analyzed.
