摘　　要：建立了电磁阀动态过程数学模型,包括电动气阀数学模型和气动液阀数学模型,运用Matlab/Simulink将两个模型联系起来求解,实现了诸如电流、电磁力、衔铁和活塞位移、速度以及控制腔压力、体积等参数变化的动态过程仿真,并运用此模型研究了线圈励磁电压、线圈匝数、电阻、气隙、气源压力、反力因素以及结构尺寸参数等对电磁阀响应特性的影响。In this article, the mathematical model of a solenoid valve including the electro pneumatic valve model and the pneumatic hydraulic valve model is presented. These two models are related by using Matlab Simulink to form the software simulation model. So that the current, the magnetic force, the displacement, the velocity, the pressure and the volume of the control cavity can be simulated. The influences of such factors as the voltage, the number of winding circle, the resistance, the width of solenoid air gap, the pressure of the compressed gas, the reaction factors and the size parameters, etc. on the response characteristics of the solenoid valve are analyzed.
