摘要
NVH仿真分析可以在设计阶段预测电机的电磁振动噪声特性,从而提出电机电磁优化设计方案。本文搭建一永磁同步电机的有限元模型,施加合理的材料属性和约束条件进行NVH仿真计算,并通过样机测试,验证仿真的准确性。
NVH simulation analysis can predict the electromagnetic vibration noise characteristics of a motor in the design stage,so as to propose the optimization design scheme of the motor electromagnetic.This paper builds the finite element model of a permanent magnet synchronous motor(PMSM),applies reasonable material properties and constraints to perform NVH simulation analysis,and verifies the accuracy of the simulation through the prototype testing.
