摘要
振动是电机的重要性能指标,对电机定子进行振动分析,可以为其结构改进和性能优化提供理论依据。在MSC.Nastran环境下,利用有限元方法进行电机定子的模态仿真,得到定子的多阶固有振动频率、振型等参数值。根据仿真图和数据,分析定子的危险位置和振型。进行定子模态试验,通过试验结果对比验证虚拟样机和数值模拟的有效性。仿真结果表明,系统不会发生共振。最后,在力学分析的基础上探讨螺栓数对结构振动的影响。
Motor vibration is an important performance indicators,and motor vibration analysis,can improve its structure and provide a theoretical basis for performance optimization.The models of the base of a type vertical motor were adopted to MSC.Nastran software to analysis modes,get multi-order natural frequencies and vibration shape of the stator based on element finite simulation,these main destroy forms and locations were gained.The effect of the vibration of the motor was also discussed according to these ele...
