摘要
随着全球的电动汽车热潮的推进,电驱动总成的NVH性能越来越受到重视,逐渐成为研究学者们的研究重点。NVH是噪声、振动与声振粗造度(Noise、Vibration、Harshness)的英文缩写,汽车驾驶的舒适性与作为电动汽车核心部件的电驱动总成有关,电驱动总成的振动噪声的表现直接影响电动汽车的NVH性能。本文通过对驱动电机进行理论分析,从而推导出驱动电机的NVH性能。
With the advancement of the global electric vehicle boom,the NVH performance of electric drive assemblies has received more and more attention,and has gradually become the research focus of researchers.NVH is the abbreviation of Noise,Vibration and Harshness(Noise,Vibration,Harshness).The comfort of car driving is related to the electric drive assembly as the core component of electric vehicles.The performance of the vibration and noise of the electric drive assembly is directly related,which affect the NVH performance of electric vehicles.In this paper,through theoretical analysis of the drive motor,the NVH performance of the drive motor is derived.
