摘　　要：将故障仿真的概念与方法引入到电液控制系统的故障研究中来，对电液伺服阀中的电磁力矩马达的驱动线圈进行了故障仿真，给出了其故障特征及其区别方法，为电液伺服阀故障研究提供了故障特征方面的依据．Torque motor is a precious unit used for transfer electrical signal into mechanical signal. Its coils are quite easy to failure but the diagnosis is very difficult. This paper gives a solution to this problem by means of fault simulation. After establishing its fault model, a numeral fault simulation as implemented. Some fault symptoms have been given, which will be helpful to the fault diagnosis of the valve.
