摘　　要：针对电液伺服阀这一典型机械、电子、磁场、液压与控制耦合的复杂系统,考虑其多领域、多层次化的特点,应用多领域建模仿真语言Modelica对电液伺服阀进行建模仿真。不同于传统的电液伺服阀控制框图建模分析方法,Modelica语言的非因果性与面向对象性,使得该方法具有强可读性,强可用性,便于修改等特点,克服了传统方法不能从底层元件反映伺服阀特性、考虑因果性、不易修改与重用的缺点。仿真结果显示,该方法可以反映电液伺服阀的动态特性,同时可以方便地通过参数修正对电液伺服阀进行优化设计,为电液伺服工程技术人员提供了电液伺服阀设计的更为高效便捷的手段。An electro-hydraulic servo valve is a typical complicated multi-domain system constructed by mechanical, electrical, hydraulic and magnetic components, the modeling and simulation of which is studied based on Modelica considering the multi-domain and multi-level features. This method leads to a readable, easy to modify and reuse model due to the object-oriented and non-causal characteristic of Modelica, and overcomes the disadvantages of the traditional method. nonobjective, casual, hard to modify and reuse. The consequences show that the dynamical characteristics of the servo valve can be obtained under this method, the optimization of the servo valve by parameter modification can be executed easily, and this method provides the engineers a more efficient way to design a servo valve.
