轮毂电机式纯电动汽车平台的建立

为了顺利地进行轮毂电机式纯电动汽车的性能研究，文章具体描述了其样车实体平台的建立过程。表明该平台选取了内转子电动机减速驱动型电动轮，采用锂电池作为动力源。在传统内燃机式的沙滩车基础上，完成了底盘和车身部分的改造和重布置，并进行了虚拟样机的整车建模。该平台的设计思路符合未来发展的趋势并具有质量轻、结构简单以及成本低的优点，能很好地完成电动汽车控制策略和其他性能的研究任务。

Establishment of the Platform for EV Equipped with Wheel-hub Motor

In order to research on EV equipped with wheel-hub motor, this paper introduces the process of building the platform model in detail, adopting inner rotor motor deceleration-driving electric wheel as the driving wheel and lithium cell as the power source. This paper describes how to rebuild the chassis and the body on the basis of traditional internalcombustion engine type ATV, and establishes some virtual models on computer. This platform, with the characteristics of light weighting, simple structure and cost efficiency, can well fulfill the controlling strategy of EV and research on other performances of EV.
