摘　　要：转向电动机振动与噪声的大小影响了驾驶者操作舒适性和安全性。为了研究影响汽车转向电动机振动模态的因素,在ANSYS Workbench软件上建立了精确的电动机各个部位的三维模型,在ANSYS Maxwell软件上进行了电动机定子铁心的径向电磁力仿真,使用宁波工程学院提供的试验设备在半消声室中进行了声学试验,通过模态仿真找出定子齿槽尺寸和材料参数对电动机径向模态的影响规律。The vibration and noise of steering motor affect the driver's operating comfort and safety.In order to analyze the affecting factors of the automotive steering motor vibration modes,this paper establishes a precise three-dimensional model of each part of the motor on ANSYS Workbench software,and carries out the radial electromagnetic force simulation of the stator core of the motor on ANSYS Maxwell software.The acoustic experiment is carried out in the semi-anechoic chamber with the experimental equipment provided by Ningbo Institute of Technology.The influence law of stator groove size and material parameters on the radial mode of the motor is obtained by modal simulation.
