摘要
为了分析某商用车动力性及燃油经济性,对其动力传动系统进行建模与仿真,经过仿真值与试验值的对比,验证了模型的正确性。在此模型的基础上,通过匹配不同的传动比方案,并采用线性加权组合方法将动力性和燃油经济性转化成单一目标函数来评价动力传动系统匹配的优劣。结果表明,综合评分为-1.98的组合方案为最优方案。该分析方法也为其他同类车型的匹配提供了依据。
In order to analyze a commercial vehicle dynamic performance and fuel economy,modeling and simulation for the power transmission system,after comparing the simulation value and the experimental value,verifies the correctness of the model. On the basis of this model,by matching the different transmission ratio scheme,the advantage and disadvantage of power train were obtained,through linear weighted combination method for dynamics property and fuel economy to convert to single target function.The results show that the solution whose score is-1. 98 is the best. This analysis provides the basis for other similar model matching.
