摘要

本文提出一种转子同频(基频)振动的在线消除策略,该策略利用电磁力执行机构给转子施加一个和转子转速同频率的旋转矢量电磁力,该力在转子测振平面上引起的振动用于抵消转子的初始振动,从而实现同频振动的在线消除。本研究首先对转子同频振动及电磁力可控特性进行分析;接着对系统进行理论分析,在此基础上建立了以转子振动响应为指标、磁极线圈电流幅值和相位为寻优参数的寻优控制模型,并提出相位整周搜寻算法;运用Matlab /Simulink软件对算法进行仿真分析;最后建立试验装置并进行实验研究,结果表明本文提出的控制策略可以有效降低转子同频振动。



Abstract

Abstract: This paper presents a strategy to eliminate synchronous vibration of rotor system online. The solution utilizes electromagnetic actuator to generate synchronous rotating electromagnetic force, and the electromagnetic force is applied to rotor synchronous unbalance vibration suppression in the rotor vibration monitoring of the plane. In this research, rotor synchronous vibration and electromagnetic controllable characteristics are analyzed firstly, and then, theoretical analysis on the rotor system is done also. Based on these analyses, an optimal control model was designed, in which rotor vibration response is regarded as control target and the amplitude and phase of coil current are regarded as optimal parameters. And current phase complete period search algorithm was proposed. Simulation is carried out. At last the test equipment is established to be used to experimental study. The experimental results show the proposed algorithm is effective for unbalance synchronous vibration suppression.
