基于有限元法的电机噪声分析及优化

Analysis and Optimization on the Motor Noise Based upon FEM

针对公司生产的电机存在噪声无法满足要求的情况,经分析确定了噪声超标的原因是由转子共振引起的。使用AnsysWorkbench软件进行仿真,确定了以更换轴承类型的方式来完成结构优化的方案。实验结果证明了该方案的有效性,可为后续同类问题的解决提供参考。

In case that the LV motor failing to meet the requirement in the field of noise,the cause of noise is analyzed.After analysis,reasons for exceeding standard is predicated,it is caused by rotor resonance.The Ansys Workbench software is applied to confirm the constructional optimization program to replace the bearings.Test results proves effectiveness of the program,providing reference to solve the same kind of problems.
