摘　　要：燃气轮机机匣在工作状况下受多种零部件的影响会产生复杂的振动,将导致机组工作噪声升高、意外停机、减小设备使用寿命等问题。文中介绍了一种利用电磁致动器对燃气轮机机匣进行主动控制的方法,通过利用机匣主要振动位置处的加速度信号作为反馈信号,对系统采用H∞算法进行振动主动阻尼。实验结果表明,提出的主动阻尼方法可显著提升机匣的动刚度,并大幅减小机匣振动。Under the working condition of gas turbine casing,complicated vibration will be generated under the influence of various parts and components,which will lead to the increase of unit operating noise,unexpected shutdown,and reducing the service life of equipment.This paper introduces an active damping method of gas turbine casing with electromagnetic actuator.In this scheme,the acceleration signal of the casing at the vibration position is read as feedback signal,and H∞control algorithm is adopted to suppress the system vibration.Experimental results show that the proposed active damping method improves the dynamic stiffness of the casing and reduces the vibration of the casing significantly.
