电磁式作动器控制转子振动的理论分析与实验研究

Theoretical and Experimental Research on ActiveVibration Control System Using Electromagnetic Actuator

本文在研制电磁式作动器及其振动控制系统的基础上，分析了电磁式作动器的力学模型，对具有不平衡转子的振动进行了控制实验研究．结果表明，电磁式作动器具有较好的可控刚度和阻尼特性；在共振频率处，转子振动幅值减少了５０％～８０％．

In this paper, the mechanics model of an electromagnetic actuator is analysed based on the developedcontrol system. The experiment of active vibration control of a rotor system with an unbalanced mass hasbeen made. Experimental results prove the good properties of this electromagnetic actuator in vibrationcontrol.
