| 論文摘要： | 摘 要：二氧化碳是造成溫室效應的主要氣體，上坡路段顯著影響載重貨車的碳排放。為研究上坡路段對載重車碳排放的影響特性，本文基于汽車動力學模型，通過計算重量功率比為148kg/kW的載重車在不同坡度路段上坡行駛過程中的瞬時速度，作為MOVES模型的基礎數據，預測得到10-90km/h共9檔初速度和0-8%共9個縱坡組合條件下的碳排放量數據，采用SPSS分析了坡度和初速度對碳排量的影響，建立了以坡度和初速度為自變量的載重車碳排放模型，利用該模型得到了碳排放量等高線圖。結果表明：載重車上坡過程中碳排量隨坡度的增加而增大，隨初速度的增加而減?。惠d重車爬坡初速度越大，碳排量對坡度的敏感性越低，低坡度條件下碳排量對初速度的敏感性比陡坡更低；環保型的公路縱坡設計建議采用高坡度和短坡長組合。研究成果可以直觀地分析縱坡和初速度對載重車碳排放的影響，指導環保型道路建設。 |
