轻型柴油载货车辆传动系参数优化的评价指标研究

Evaluation Indexes of Parameter Optimization in the Powertrain of Light Diesel Trucks

对轻型柴油货车传动系参数优化中的评价指标进行了研究。根据车型的使用特点，把载荷工况引入了优化的评价指标中，从统计分析的角度，确定载荷工况系数；利用价值原理，从整车性能对比中得到动力性和燃料经济性的权系数。对实车进行了匹配选择。结果表明，方法可行。

The evaluation indexes of parameter matching optimization in automobile powertrain were studied. The load conditions were leaded into optimization target. From the view of statistic analysis, the load condition coefficiency was obtained. The weight coefficiencies of dynamics and fuel consumption were received by using the value principle and comparing the automobile performance. The matching selection was applied on the actual vehicle.
