摘要

为了研究电动汽车内置式永磁同步电机(IPMSM)在不同调速方式和工况下的振动和噪声特性，建立了样机的“空间矢量脉宽调制(SVPWM)控制-电磁场”联合仿真模型，仿真电机的实际运行情况。在此基础上，建立了振动与噪声的多物理场耦合模型，并提出了根据不同模态阶数添加阻尼的方法，计算了样机在不同调速方式和工况下的振动与噪声特性。

Electromagnetic Vibration and Noise Analysis of IPMSM for Electric Vehicles under Different Working Conditions

In order to study the vibration and noise characteristics of Interior Permanent Magnet Synchronous Motor(IPMSM) for electric vehicles(EVs) under different speed regulation modes and operating conditions, a co-simulation model of ”space vector pulse width modulation(SVPWM) control-electromagnetic field” of the prototype is built to simulate the actual operation of the motor. Based on this model, a multi-physics field coupling model of vibration and noise is established and proposing a method of adding damping according to different modal orders to calculate the vibration and noise characteristics of the prototype under different speed regulation modes and operating conditions.
