摘　　要：通过建立径向磁悬浮轴承—Jeffcott转子动力学模型,为磁悬浮转子瞬态响应分析提供理论指导。并在SAMCEF ROTOR有限元分析软件中建立Jeffcott转子结构模型,定义转子不平衡条件及磁悬浮轴承支撑参数,分析转子在不同的加速度加速条件下的瞬态位移及模态变化规律。分析结果为电机加速方案的优化奠定基础。： Establishing the rotor dynamics model of Jeffcott rotor as the theoretical guidance of transient response analysis of Magnetic Suspension Rotor.And making the structural model of Jeffcott Rotor by the finite element software named SAMCEF ROTOR.Then analyzing the transient displacement and modality variation regularity of the rotor under different acceleration conditions by defining the unbalanced condition and support parameters of magnetic bearing on the rotor.The analysis results lay a foundation for the acceleration program optimization of the motor.
