【摘要】：隨著城市化進(jìn)程的不斷加快，城市人口不斷增加，汽車數(shù)量激增，交通擁堵經(jīng)常發(fā)生，逐漸成為城市建設(shè)的一大問題。公交先行已成為城市減緩交通擁堵的重要措施。建立體現(xiàn)城市公交車輛行駛特征的代表性循環(huán)工況，以針對城市車輛運(yùn)行特點(diǎn)進(jìn)行城市客車的動(dòng)力系統(tǒng)匹配，對改善車輛的經(jīng)濟(jì)性和排放特性具有重要意義。 為給客車企業(yè)提供車輛動(dòng)力匹配的基礎(chǔ)數(shù)據(jù)，論文以企業(yè)項(xiàng)目“西安市循環(huán)工況的研究”為背景，在了解西安城市公交車輛運(yùn)行情況的基礎(chǔ)上，選取典型路段建立西安城市公交車輛的循環(huán)工況。對西安市的客流規(guī)律、公交線路及運(yùn)行公交車輛等進(jìn)行調(diào)研，得到西安城市公交的基本特征，并以CNG城市公交為研究對象，利用GPS無線接收模塊進(jìn)行數(shù)據(jù)采集，將數(shù)據(jù)分割成若干個(gè)站點(diǎn)運(yùn)動(dòng)區(qū)間并求解其特征值。采用SPSS中的主成分分析和聚類分析將站點(diǎn)運(yùn)動(dòng)區(qū)間分成代表不同運(yùn)行特征的類別，以此構(gòu)建西安典型路段城市公交循環(huán)工況，并與其他典型工況對比得出西安城市公交循環(huán)工況自身特點(diǎn)。 利用ADVISOR建立試驗(yàn)車輛仿真模型，并在已建立的西安城市公交循環(huán)工況和國家標(biāo)準(zhǔn)四工況下分別進(jìn)行百公里燃?xì)庀牧康姆抡妫c實(shí)際百公里燃?xì)庀牧肯啾鹊玫絿覙?biāo)準(zhǔn)四工況不能真實(shí)反映西安城市公交運(yùn)行特征�；谝呀⒌奈靼渤鞘泄谎h(huán)工況，，通過對試驗(yàn)車輛動(dòng)力性和燃?xì)饨?jīng)濟(jì)性的分析計(jì)算，在發(fā)動(dòng)機(jī)功率配備方面提出既滿足動(dòng)力性又能提高燃?xì)饨?jīng)濟(jì)性的改進(jìn)建議，論文研究對節(jié)能減排，改善環(huán)境有很重要的作用。
[Abstract]:With the rapid development of urbanization, the urban population is increasing, the number of cars is increasing, and traffic jams often occur, which has become a major problem in urban construction. Public transportation has become an important measure to reduce traffic congestion in cities. It is of great significance to improve the economic and emission characteristics of urban buses by establishing typical cycle conditions that reflect the driving characteristics of urban public transport vehicles in order to match the power system of urban buses according to the running characteristics of urban vehicles. In order to provide bus enterprises with the basic data of vehicle power matching, this paper takes the enterprise project "the study of Xi'an City cycle working condition" as the background, on the basis of understanding the running situation of Xi'an city public transport vehicles. Select typical sections to establish the cycle of Xi'an urban public transport vehicles. The basic characteristics of Xi'an urban public transport are obtained by investigating the rules of passenger flow, bus lines and running buses in Xi'an, and taking CNG urban public transport as the research object, using GPS wireless receiving module to collect data. The data is divided into several stations moving intervals and their eigenvalues are solved. In this paper, the principal component analysis and cluster analysis in SPSS are used to divide the station movement interval into categories representing different operation characteristics, so as to construct a typical section of Xi'an urban public transport cycle. And compare with other typical working conditions to get the characteristics of Xi'an urban public transport cycle. The simulation model of test vehicle is established by using ADVISOR, and the 100 km gas consumption is simulated under the established cycle condition of Xi'an city public transportation and the national standard four working conditions, respectively. Compared with the actual consumption of 100 km gas, the four working conditions of national standard can not truly reflect the running characteristics of Xi'an urban public transportation. Based on the established working conditions of Xi'an city public transportation cycle, through the analysis and calculation of the power performance and gas economy of the test vehicle, the paper puts forward some suggestions to improve the power allocation of the engine, which can not only meet the power performance but also improve the fuel gas economy. The research in this paper plays an important role in saving energy and reducing emissions and improving the environment.
