不平衡磁悬浮转子自动平衡仿真分析

Simulation Analysis of Automatic Balancing of Unbalanced Magnetic Suspension Rotor

由于转子不平衡的存在,导致磁悬浮轴承系统存在不平衡振动,严重影响磁悬浮轴承系统的平稳运转。对自动平衡控制算法进行研究,解释了自动平衡控制算法实现主动抑振的原理,发现自动平衡算法在抑制磁悬浮轴承系统振动的同时,也可提升转子旋转精度,并搭建了含有自动平衡控制算法的主动磁悬浮轴承控制系统。仿真结果显示:对比开启补偿算法前,开启补偿算法后系统振动减少约67%的同时,转子回转精度提升了约50%,验证了理论计算的正确性。

Due to the unbalance of the rotor,the magnetic bearing system has unbalanced vibration,which seriously affects the smooth operation of the magnetic bearing system.The automatic balance control algorithm is researched,and the principle of the automatic balance control algorithm to achieve active vibration suppression is explained.It is found that the automatic balance algorithm can improve the rotor rotation accuracy while suppressing the vibration of the magnetic bearing system,and build an active magnetic bearing control system containing the automatic balance control algorithm.The simulation results show that compared with before and after the compensation algorithm is turned on,the system vibration is reduced by about 67%,and the rotor rotation accuracy is improved by about 50%,which verifies the correctness of the theoretical calculation.
