摘　　要：用ANSYS/Rotordynamics分析软件建立了磁悬浮柔性转子的有限元模型;对转子的运动特性——临界转速、模态轨迹和振型进行了系统的计算和理论分析;研究了磁悬浮柔性转子模态轨迹的特性以及对位移测试信号的影响;同时,为同类磁悬浮柔性转子的悬浮控制提供理论参考。The finite element model of a magnetically levitated flexible rotor is established with the help of the analysis software ANSYS/Rotordynamics. The characteristics of the rotor are systematically calculated and theoretically analyzed, such as critical speed, modal orbit and vibration modal. The features of the modal orbit of the rotor and its influence on the displacement test signals are studied. Thus, a theoretical reference is provided for the levitation control of the same kind of magnetically levitated flexible rotors.
