超高速电动汽车动力系统的结构与性能研究

A Research on the Structure and Performance of Powertrain in a Ultrahigh Speed Electric Vehicle

超高速电动汽车是为突破电动车极限速度而研发,旨在使车辆达到400mph的速度。车辆动力学模型、传动系统模型和制动系统模型的设计直接影响车辆的动力性能。本文中采用仿真与台架试验相结合的方式,获取车辆的动力性能。结果表明,新一代超高速电动汽车的最高时速可超过400mph。

Ultrahigh speed electric vehicle is developed for breaking through the extreme speed limit of e-lectric vehicle, aiming at the target of maximum speed reaching 400mph. The models of vehicle dynamics, drivetrain and braking system directly affect the power performance of vehicle. In this paper, the way of combining simulation with bench test is adopted to obtain the power performance of vehicle. The results show that the newest generation of ultrahigh speed electric vehicle has reached a maximum speed higher than 400mph.
