論文摘要:

摘  要:二氧化碳是造成溫室效應(yīng)的主要?dú)怏w,上坡路段顯著影響載重貨車的碳排放。為研究上坡路段對(duì)載重車碳排放的影響特性,本文基于汽車動(dòng)力學(xué)模型,通過計(jì)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(shí)速度,作為MOVES模型的基礎(chǔ)數(shù)據(jù),預(yù)測(cè)得到10-90km/h共9檔初速度和0-8%共9個(gè)縱坡組合條件下的碳排放量數(shù)據(jù),采用SPSS分析了坡度和初速度對(duì)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(jié)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??;載重車爬坡初速度越大,碳排量對(duì)坡度的敏感性越低,低坡度條件下碳排量對(duì)初速度的敏感性比陡坡更低;環(huán)保型的公路縱坡設(shè)計(jì)建議采用高坡度和短坡長(zhǎng)組合。研究成果可以直觀地分析縱坡和初速度對(duì)載重車碳排放的影響,指導(dǎo)環(huán)保型道路建設(shè)。
