【摘要】:由于山區(qū)高速公路建設(shè)前期投資規(guī)模大、施工技術(shù)復(fù)雜并且后期養(yǎng)護(hù)成本高,往往需要通過(guò)比較設(shè)計(jì)方案全壽命周期成本來(lái)實(shí)現(xiàn)投資的最優(yōu)化,能耗成本是全壽命周期成本的重要組成部分。此外,能耗對(duì)于公路建設(shè)區(qū)域的生態(tài)環(huán)境也將產(chǎn)生較大的影響。從經(jīng)濟(jì)、節(jié)能和環(huán)保三個(gè)角度出發(fā),適合我國(guó)山區(qū)高速公路的能耗測(cè)算方法對(duì)于高速公路設(shè)計(jì)方案評(píng)價(jià)具有重要的意義,而開發(fā)面向山區(qū)高速公路的能耗仿真軟件可以提高測(cè)算的精度和效率。本文研究課題來(lái)源于交通運(yùn)輸部應(yīng)用基礎(chǔ)研究項(xiàng)目(編號(hào):2015319812200)“基于VSP的山區(qū)高速公路汽車能耗評(píng)價(jià)方法研究”。在能耗測(cè)算方法研究上,采用《JTG B05-2015公路項(xiàng)目安全性評(píng)價(jià)規(guī)范》中關(guān)于運(yùn)行速度V85的預(yù)測(cè)方法,將各路段以一米為步長(zhǎng)進(jìn)一步劃分獲得近似連續(xù)車速,在此基礎(chǔ)上獲得各車型的VSP分布。開展實(shí)地試驗(yàn),選取Ⅳ型客車、六軸貨車作為試驗(yàn)車型,采用濰柴CAN總線適配器連接CAN總線讀取車輛ECU中的數(shù)據(jù)流,在西漢高速K1133—K1176路段進(jìn)行試驗(yàn)數(shù)據(jù)采集,完善部分大型車車型油耗率數(shù)據(jù)庫(kù)。利用VC++軟件開發(fā)平臺(tái),對(duì)基于VSP的山區(qū)高速公路能耗測(cè)算仿真系統(tǒng)進(jìn)行開發(fā),采用DAO數(shù)據(jù)庫(kù)訪問(wèn)對(duì)象對(duì)數(shù)據(jù)庫(kù)進(jìn)行管理,完成添加、修改、刪除和導(dǎo)出數(shù)據(jù)表等操作,將系統(tǒng)分為數(shù)據(jù)的輸入與管理模塊、數(shù)據(jù)的處理模塊、結(jié)果輸出模塊和用戶管理模塊,實(shí)現(xiàn)了道路數(shù)據(jù)庫(kù)管理、道路能耗仿真、測(cè)算結(jié)果輸出及用戶管理等功能。應(yīng)用基于VSP的山區(qū)高速公路能耗測(cè)算仿真系統(tǒng)對(duì)于西漢高速部分道路能耗進(jìn)行測(cè)算,在一定的交通量和車型比例條件下分別進(jìn)行仿真,分析比較計(jì)算結(jié)果。仿真結(jié)果表明大型車的運(yùn)行速度范圍在25km/h-80km/h之間,加速度范圍在-0.5m/s2-0.3m/s2之間;小型車的運(yùn)行速度范圍在55km/h-95km/h之間,加速度范圍在-0.9 m/s2-0.8 m/s2之間;小型車的車型比例基本高于其能耗比例而大型車車型比例基本低于其能耗比例;6軸貨車空載和滿載狀態(tài)下各速度區(qū)間的能耗分布狀況基本相同;6軸貨車和Ⅳ型客車的能耗最小和能耗最大占比均分別出現(xiàn)在最小速度區(qū)間和最大速度區(qū)間。各車型的能耗測(cè)算相對(duì)誤差均在15%以內(nèi),證明了仿真結(jié)果的有效性。
[Abstract]:Due to the large scale of early investment, complex construction technology and high maintenance cost in mountainous expressway construction, it is often necessary to optimize the investment by comparing the life-cycle cost of the design scheme. Energy cost is an important part of life cycle cost. In addition, energy consumption will also have a greater impact on the ecological environment of highway construction areas. From the three angles of economy, energy saving and environmental protection, the energy consumption calculation method suitable for mountain expressway in our country is of great significance to the evaluation of highway design scheme. The development of energy consumption simulation software for mountain expressway can improve the accuracy and efficiency of calculation. The research topic of this paper is derived from the basic research project of the Ministry of Communications and Transportation (No.: 2015319812200), "study on the Evaluation method of Automobile Energy consumption in Mountain Expressway based on VSP". In the research of energy consumption calculation method, using the prediction method of running speed V85 in "JTG B05-2015 Highway Project Safety Evaluation Standard", each section is further divided with one meter step to obtain approximate continuous speed. On this basis, the VSP distribution of each vehicle model is obtained. The field test was carried out, and the type 鈪,
