磁力轴承转子动力学分析中不平衡载荷的设定

Determination of Unbalance Load in Rotor Dynamics Analysis for Magnetic Bearing System

摘要: 参考航空发动机上常用的关于不平衡响应的分析方法，结合磁力轴承支承刚度远低于普通轴承的特点，提出了设定磁轴承支承下转子不平衡载荷的一种工程方法。这一方法可为进一步研究磁力轴承-转子系统设计中的转子不平衡响应、转子运行的稳定域度及进行转子动平衡设计等打下良好基础。

Abstract: Considering the magnetic bearing stiffness is far below the normal bearing, and reference to the airplane engine research results, an engineering method was presented to determine the rotor unbalance load for dynamics analysis. The method lays a sound foundation for further study on the magnetic bearing-rotor system design and its rotor dynamics researches.
