摘　　要：建立了四轮轮毂电机驱动电动车的仿真模型,并在考虑前端进气,车轮旋转以及地面效应影响情况下,得到了最接近真实情况下电动车行驶时的外流场及轮边流场.对轮边驱动结构给流场带来的影响以及轮毂电机通风散热条件进行了分析.所得结果为轮边驱动电动车空气动力学性能优化以及轮边系统热管理提供了重要依据.To analyze the flow fields of an electric driven vehicle with four-in-wheel-motor, the computational results of flow fields were obtained with front end airflow simulation, so the external flow around the wheels of an in-wheel-motor vehicle in detail conditions was obtained. At the same time, the results of an in-wheel-motor vehicle and a conventional vehicle were compared for local and global flow fields. Furthermore, the ventilation of in-wheel-motor system was annlyzed, which provided aerodynamic data for thermal dissipation of brake and in-wheel motor.
