摘　　要：以三位四通换向阀为研究对象,分析了电磁阀阀芯的运动机理,采用多物理场耦合的数学模型方法建模,建立了电磁换向阀阀芯工作过程的动态响应数学模型。在AMESim软件环境下对电磁阀建模。运用所建立模型,对影响电磁阀阀芯位移的因素进行分析,在模型中更改电磁阀弹簧刚度,得到一组阀芯位移曲线。结果表明:当弹簧老化后,同样输入下阀芯位移会增大,使液压系统产生安全隐患。最后对仿真结论进行了试验验证。The three position four-way electromagnetic directional valve was taken as the research object, The motion mechanism of solenoid valve spool was analyzed, model was established by using multiphysics coupling mathematical model establishment method, and a mathematical models of dynamic response of solenoid valve spool work process was established. In AMESim software environment, solenoid valve model was established. Using the established model, the factors affecting the solenoid valve spool displacement was analyzed. By changing in the model of spring stiffness, a group of spool displacement curves was gotten. The result shows that when spring aging, spool displacement will increase in the same input, let the hydraulic system security risk. Finally, the modle is verified by experiment.
