摘要

首先介绍了动力总成结构;根据车辆参数和驾驶要求,对动力总成的一些重要参数进行匹配。在电机参数选择的基础上,建立了传动比的约束条件。以传动比优化为目的,在MATLAB/Simulink软件平台上建立了变速器模型和整车动力学模型。在ISIGHT软件中采用多目标优化遗传算法NSGA-II,确定了最优传动比为7.34i1 13.9和5.44i2 8.49,取最优时,主减速比的比值为:传动系统传动比ig1 = 3.09 ig2 =1.83 i1 =11.75 i2 =6.98 iF =3.8 ig1 = 3.09 ig2 =1.83

Matching Design and Optimization Research of Gearbox for Electric Vehicle
Powertrain structure is introduced first; some important parameters of the power train are matched, according to the vehicle parameters and the driving requirements. The constraints of the transmission ratios are built up following the selecting of the motor parameters. For the purpose of the transmission ratios optimization, the transmission model and the whole vehicle dynamic mode is established on the software platform of MATLAB/Simulink. The optimal transmission ratios are identified by employing the multi-objective optimization genetic algorithm NSGA-II in the software ISIGHT, and the optimal transmission ratios are 7.34i1 13.9 and 5.44i2 8.49 .The optimum , .when it be taken as , , and the ratio of the main deceleration ratio is transmission ratio of the transmission system ig1 = 3.09 ig2 =1.83 i1 =11.75 i2 =6.98 iF =3.8 ig1 = 3.09 ig2 =1.83
