汽车产业面临越来越严峻的环境及能源挑战，促使各大车企在新能源汽车上投入更多的资金及技术。驱动电机是新能源汽车的核心部件之一，其工作在高温、振动的环境下，功率密度高。因此，电机结构设计关系到强度、振动噪声、耐久性等。阐述了某驱动电机的结构特点及设计开发过程。通过CAE软件仿真分析了整车不同工况下电机壳体静强度，扫频、随机振动工况时壳体承受的应力，以及整机模态。驱动电机通过专项振动试验，证明其结构强度及模态满足设计目标。

The automobile industry is facing more and more severe environmental and energy challenges, urging the major automobile enterprises to invest more capital and technology in new energy vehicles. The drive motor is one of the core components of new energy vehicle. The motor works in high temperature and vibration environment with high power density. Therefore, the design of motor structure is related to strength, vibration and noise, durability, etc. The structural characteristics and the design and development process of a drive motor are described. The static strength of the motor shell under different working conditions of the whole vehicle, the stress on the shell under sweep-frequency vibration and random vibration conditions, and the modes of the whole motor are analyzed by CAE simulation. Through the special vibration test of the drive motor, it is proved that its structural strength and modes meet the design objectives.
