摘　　要：基于现代控制理论的状态空间法,建立了螺纹插装式二位二通电液换向阀开闭过程的动态特性数学模型,选用四阶龙格库塔算法,采用C++编程,对电液换向阀开关过程动态特性进行仿真,研究了阀的结构参数和系统的性能参数变化对阀的开启和关闭动态过程性能的影响,分析确定了阀的结构参数,为同类阀的动态特性研究提供了一种有效手段,对提高阀的动态特性具有非常重要的意义。Based on state space method of modern control theory, the mathematical model for the two way/two position electro-hydraulic operated directional valve in thread cartridge was established. The influence on the dynamic characteristics of the valve was analyzed with respect to the parameter varieties of the components with the simulation and 4 steps Runge-Kutta method was adopted with C＋＋ procedure edited so as to obtain the optimum combination parameters of the valve. The effective means is provided for study of dynamic performance with the same class valves and it is the important significance to improve dynamic characteristics of valve.
