摘　　要：为研究减速器齿轮尺寸对电动汽车传动系统扭转振动的影响,建立分布式驱动电动汽车传动系统集中质量模型,选取3个不同的齿轮副等效惯量,计算传动系统固有特性和模态振型,分析不同齿轮参数下传动系统的振动特性与转角的时域响应。结果表明,减速器的转动惯量过大或过小会增加整车扭转振动频率、增加传动系统扭转振动的幅值。实验结果具有重要的理论研究价值和工程应用前景。To study the effect of reducer gear size on torsional vibration of electric vehicle transmission systems,firstly,a centralized mass model for the distributed drive electric vehicle transmission system is established.Three groups of gear inertias are selected to calculate their transmission system inherent charac-teristics and modal shapes,to analyse vibration characteristics of transmission system and time-domain response of rotation angle under different parameters.The results show,too large inertia or too inertia of the reducer will increase the frequency of the vehicle torsional vibration and increase the amplitude of the torsional vibration of the transmission system.The experimental results have important value of theoretical research and prospects for engineering application.
