摘要
针对传统的铁心特性仿真算法中单一设置材料属性参数,以及简单整体等效等问题,为了提高大型电机叠片铁心的振动特性仿真结果的准确性,为电机设计提供重要的参考数据,提出一种改进的电机铁心振动特性仿真方法。该方法包括将铁心视为一种均质的正交各向异性层压板结构材料,利用推荐的拟合曲线得到材料属性参数,对绕组进行分部分设置材料属性,对浸漆进行整体等效等措施,建立仿真模型,进行了铁心振动特性仿真分析。结合铁心样件模态实验,验证了这种新方法的正确性和精确性。
In view of the shortcomings in the traditional vibration characteristics simulation methods, like setting material property parameters monolithically, simple equivalent as a whole, and so on, in order to improve the accuracy of the simulation results of vibration characteristics of large motor＇ s laminated core, and also to provide important reference data for the motor design, this paper proposes a reformative simu- lation method of motor pole core vibration characteristics. The pole core was considered as a homogeneous orthotropic laminates structure material, and material property parameters were obtained by fitting curve recommended. Windings material properties were set apart, and the overall equivalent measures of dip- ping lacquer was talen. Then the simulation model was established, the vibration characteristics of core was simulated and analyzed. Combining with pt modal experiments, the new method validates its veracity and accuracy.
