| 论文摘要 ： | 摘 要 ：二氧化碳是造成温室效应的主要气体，上坡路段显著影响载重货车的碳排放 。为研究上坡路段对载重车碳排放的影响特性，本文基于汽车动力学模型 ，通过计算重量功率比为148kg/kW的载重车在不同坡度路段上坡行驶过程中的瞬时速度，作为MOVES模型的基础数据 ，预测得到10-90km/h共9档初速度和0-8%共9个纵坡组合条件下的碳排放量数据，采用SPSS分析了坡度和初速度对碳排量的影响，建立了以坡度和初速度为自变量的载重车碳排放模型，利用该模型得到了碳排放量等高线图。结果表明 ：载重车上坡过程中碳排量随坡度的增加而增大 ，随初速度的增加而减小；载重车爬坡初速度越大，碳排量对坡度的敏感性越低 ，低坡度条件下碳排量对初速度的敏感性比陡坡更低；环保型的公路纵坡设计建议采用高坡度和短坡长组合 。研究成果可以直观地分析纵坡和初速度对载重车碳排放的影响 ，指导环保型道路建设 。 |
