- 摘要:
- 针对电机转子中硅钢片叠压及拉杆-叶轮的特殊结构形式,借助有限元方法对硅钢片装配过程进行仿真,获得硅钢片叠压结构横向弯曲刚度随硅钢片离散数目的变化规律,通过曲线拟合外推得到实际硅钢片叠压结构横向弯曲刚度; 根据叶轮与转轴对接面的大小,对叶轮进行分割。以质量和刚度等效为原则,实现了硅钢片叠压结构和拉杆-叶轮结构的简化建模,并通过转子部件及整体的自由模态试验对简化分析模型进行了验证。最后通过转子的运转试验对前两阶临界转速的仿真结果进行了验证,前两阶临界转速的仿真结果与试验误差小于3.1%。
- Abstract:
- According to the special structure of silicon steel sheet lamination(SSSL)and nutted rod-impeller(NRI)in the motor rotor, the finite element method was used to simulate the assembly process of SSSL.The regularity that the lateral bending stiffness varying with the discrete number of the whole silicon steel sheet structure was explored, and the lateral bending stiffness of SSSL was achieved by curve fitting and extrapolating.The impeller was also divided according to their interface size.Based on the principle of mass and stiffness equivalent, the simplified models of SSSL structure and NRI structure were achieved, and the simplified analysis model was verified through the free modal test of rotor components and whole structure.Finally, the simulation results of the first two critical speeds were verified by the rotor running test, and the deviation between the experimental and the simulation results was less than 3.1%.
