摘　　要：永磁同步电机因其优良的性能成为电动汽车首选的动力源,但电机的高频电磁噪声会严重影响车内人员的驾乘体验。对一台8极48槽的PMSM进行电磁力分析、模态分析和振动噪声仿真,利用正交表与非参数回归拟合响应面相结合的方式,对电机径向电磁力谐波进行优化,优化后的电机表面振动速度降低了37.7%,峰值噪声降低了8.5%,达到减振降噪的目标。Permanent magnet synchronous motor has become the preferred power source for electric vehicles due to its excellent performance.However,the high-frequency electromagnetic noise of the motor will seriously affect the driving experience of the people in the vehicle.Electromagnetic force analysis,modal analysis and vibration noise simulation was conducted on an 8-pole,48-slot PMSM,and the radial electromagnetic force harmonics of the motor was optimized using a combination of orthogonal table and non-parametric regression fitting response surface.The surface vibration speed of the optimized motor was reduced by 37.7%,and the noise was reduced by 8.5%,achieving the goal of vibration reduction and noise reduction.
