电动汽车动力性能仿真分析

Simulation and Analysis of Dynamic Performance of Electric Vehicle

为了使电动汽车满足动力需求,需要对其动力性能做深入的研究。以车辆系统动力学为理论基础,基于ADVISOR软件,建立了汽车部件和整车模型。选择道路循环工况,设置加速性能和爬坡性能的测试参数,运行仿真,并对仿真结果进行分析,分析结果表明电动汽车的动力性符合实际工作要求。在电动汽车设计和开发阶段,采用该研究方法得到的仿真结果,可以作为设计人员重要的参考依据。

The dynamic performance of electric vehicle is essential and needs to be researched when the power demand of electric vehicle must be satisfied.On the theoretical basis of vehicle system dynamics, the components of electric vehicle and vehicle model are built up based on the software of ADVISOR After choosing the road driving cycle and setting the parameters of acceleration and gradeability,the simulation of dynamic performance is run, and then the output results of simulation is analyzed.The obtained conclusions are in line with the actual working condition.In the design and research phase of electric vehicle ,the re- search method and the simulation results can be used as the significant reference and guidance for designers.
