摘要：本研究以一台纯电动汽车为研究对象，利用GT-SUITE仿真软件搭建整车仿真模型，在驱动电机性能参数不变的前提下，研究整车动力性能对整车质量、风阻系数、滚动阻力系数、减速器减速比等影响因子的敏感度。结果表明，最高车速对风阻系数和减速比敏感度较高，对滚动阻力系数和整车质量敏感度较低。加速性能对整车质量和减速比敏感度较高，对风阻系数和滚动阻力系数敏感度较低。爬坡性能对整车质量和减速比敏感度较高，对风阻系数和滚动阻力系数敏感度较低。唐山贷款买车

Abstract:An electric vehicle was researched in this study,and the whole vehicle simulation model is built in GT-SUITE. Under the premise of the same E-motor characteristics,the influence factors of vehicle dynamic performance on vehicle weight,drag coefficient,rolling resistance and reducer ratio are studied.The results show that the maximum speed is sensitive to the drag coefficient and the reduction ratio,and it is less sensitive to the rolling resistance coefficient and the vehicle quality.Acceleration performance is more sensitive to vehicle quality and reduction ratio,and it is less sensitive to wind resistance coefficient and rolling resistance coefficient.The climbing performance is highly sensitive to the vehicle mass and the reduction ratio,and it is less sensitive to the drag coefficient and the rolling resistance coefficient.
