纯电动汽车综合性能试验台的国内外现状与改进

Present situation and improvements of test bench for pure EV

针对纯电动汽车研究开发的需要,介绍了台架试验的必要性,分析了目前纯电动汽车综合性能试验台架的国内外研究现状,提出了主要由机架、道路模拟装置、加载装置、惯性模拟装置等组成的纯电动汽车综合性能试验台架,结合电动车试验实际要求,指出了电动轮台架试验是轮毂电机驱动的电动汽车研制阶段中的重要环节,并介绍了一种具备多项改进设计的电动轮综合性能试验台的方案。研究结果表明,该方案能够真实地模拟实际汽车行驶的各种工况,而且还具备电机试验、垂直加载试验、机电耦合制动试验、侧向力试验等多种拓展功能,对研究轮毂电机驱动的纯电动车各项性能具有较大的实际作用。

Aiming at the need of pure electric vehicle research and development,the necessity of bench test was introduced.After the analysis of the current electric automobile comprehensive performance test bench of the research status at home and abroad,the pure electric automobile comprehensive performance test-bed was established by frame,road simulator,loading device,inertia simulation device,etc..Combined with the practical requirements of electric vehicle test,it was presented that the electric wheel bench test is important to the developmerit of electric vehicles.A number of improved design scheme of electric wheel comprehensive performance test rig was introduced.The results show that it can truly simulate the car working conditions,but also has the motor test,vertical load test,mechanical and electrical coupling brake test,lateral force test and so many kinds of expanding function,which has great practical effect for studying the performance of pure electric vehicles driven by the wheel motor.
