摘　　要：电磁换向阀的动态特性分析是电磁换向阀设计的关键 ,为明确各设计参数对新型节能电磁换向阀性能的影响 ,首先给出了新型节能电磁换向阀的数学模型 ,采用拓扑网络法 ,通过求解电磁机构的动态微分方程 ,对该阀进行了动态特性仿真 ,并分析了磁钢厚度、磁钢截面积、线圈匝数和线圈电阻四参数变化对阀动态特性的影响 ,同时通过试验结果验证了数学模型及仿真方法的正确性 ,从而提出了通过减小磁钢截面积 ,增大激磁线圈匝数 。Dynamic analysis is very important for the design of a new type of energy saving solenoid directional control valve. In order to know how different design parameters influence the dynamic characteristics of a new type of valve, a mathematics model is first established, and then using the method of equivalent topology net, dynamic differential equations are solved for a new type of electromagnet. Dynamic characteristics of a new type of valve are analyzed. The changes in performances of a new type of valve with the variations of four parameters: thickness of permanent magnet, section area of permanent magnet, coil circles and coil resistant are shown. At the same time, experimental results show that the mathematics model and simulation method of a new type of valve are available and correct. The improvement of dynamic characteristics of a new type of valve by changing the design parameters is achieved by decreasing the section area of permanent magnet, increasing the circles of coil, decreasing the resistant of coil and choosing a suitable thickness of permanent magnet.
