磁致伸缩在电机电磁振动中的贡献分析

摘要

Magnetostriction numerical calculation method of magnetic materials was discussed. On account of a permanent magnet motor, the optimized thermal match finite element method was presented to calculate magnetostric-tive force and maxwell force and the vibration response. It was significance to study on vibration and noise reduction of motor.%对磁性材料磁致伸缩的数值计算方法进行了探讨,并以某永磁电机为研究对象,采用改进的热比拟有限元法进行了电机内部磁致伸缩力和麦克斯韦力的数值计算研究,并进行了振动响应的贡献度对比分析,对电机的减振降噪研究具有一定的指导意义.
