Abstract

Abstract: According to electric vehicle dynamic requirements and the disadvantages of system resonance, a matching method of power-train for electric vehicles was put forward based on frequency matching of drive train system. Taking mechanical and electrical drive system for an electric car as an example, software ADVISOR was employed to conduct simulation analysis of drive cycle of the dynamic and economic performance; the result was in accordance with actual data. Both the simulation result and test data indicated that dynamic and economic performance of the vehicle could meet the requirements; there was no resonance of the power-train system; feasibility match method was verified.

Key words: electric car, dynamic performance, matching, frequency

摘要： 根据电动汽车动力性能要求,考虑到动力传动系统共振的危害,结合传动系统频率匹配,提出了电动汽车动力传动系统参数匹配计算方法。以某公司电动汽车机电传动系统为例,在ADVISOR软件中建立整车模型,进行循环工况下动力经济性能仿真分析。通过仿真和试验可知,该车动力性和经济性均能满足设计要求且动力传动系统没有共振产生,验证了匹配的可行性。
