| 摘 要： | 振动是电机的重要指标,对电机转子进行振动分析为其结构改进和性能优化提供理论依据。运用Ansys有限元分析软件对永磁同步电机转子进行模态分析,得到该电机转子振动系统的低阶固有频率和模态振型,分析了电机振动特性。 通过电机转子模态试验,求得电机低阶固有频率,对比仿真与试验结果,验证有限元分析结果的可靠性。由结果分析可知,研究对象在额定转速下未产生共振,验证了其结构设计的合理性。研究内容对永磁同步电机的设计和优化有一定的指导意义。

| Abstract: | Motor vibration was an important performance indicators and motor vibration analysis could improve its structure and provide a theoretical basis for performance optimization. In order to understand the vibration characteristics of the motor, the first six order natural frequencies and corresponding vibration modes of the motor rotor vibration system were obtained, with the modal analysis of the rotor of the permanent magnet synchronous motor carried on by the Ansys finite element analysis software. The accuracy of the Ansys finite element analysis was verified by the hammering method of modal experiment. The result of analysis showed that the motor dod not appear resonance phenomenon, so the design of the motor rotor was reasonable. This research content has certain guiding significance for the design and optimization of permanent magnet synchronous motor. |
