摘要
在保证动力性的前提下降低客车的油耗,选择驱动功率损失率和混合工况油耗作为综合优化目标,以整车性能要求以及变速器各挡传动比间隔要求为约束条件,并基于Matlab与C#混合编程对传动系参数进行优化软件的设计与开发。实例计算结果表明:优化后目标函数值降低明显,且选择较大的经济性加权因数优化效果更佳。适当增大主减-速器传动比,并增大传动比范围,可以在一定程度上提高客车的性能。
Based on the technique of mixed programming by Matlab and C#, the transmission parameters optimization software is developed to improve the performance of passenger car. The power loss rate and the fuel economy are transformed into objective function, and the requirements of the vehicle performance and the gearbox ratio interval are used as constraint conditions. The re- sult of verification example shows that the objective function value is reduced after optimization and the effect of optimization with larger weighted factor of economy is more significant. The performance of passenger car can be improved by increasing the main reducer gear ratio and the transmission ratio range.
