罚函数法在汽车传动系统最优匹配中的应用

Application of SUMT in the optimal matching of automobile powertrain

汽车传动系参数的选择是否合理对汽车的动力性经济性的改善影响较大。本文运用罚函数法对汽车传动系统参数进行优化，通过实例计算表明，应用该方法优化传动系统参数可以使整车综合性能得到较大的提高，从而证明运用罚函数法进行汽车传动系参数优化是可行的。

The optimal matching of automobile powertrain can greatly improve the power performance and fuel economy of the vehicle. The paper presents a new way——SUMT to optimize parameters of the automobile powertrain. Based on the calculation of illustration, the feasiblility of this way is proved and the vehicle performance is obviously improved.
