【摘要】：分析純電動(dòng)公交車能耗經(jīng)濟(jì)性是一項(xiàng)復(fù)雜的工程,并且純電動(dòng)公交車在實(shí)際運(yùn)行過程中實(shí)際運(yùn)行參數(shù)具有隨機(jī)性和不確定性。因此除了驅(qū)動(dòng)電機(jī)的類型、電池的參數(shù)、傳動(dòng)系統(tǒng)匹配程度等傳統(tǒng)因素對純電動(dòng)車耗能經(jīng)濟(jì)性影響之外,利用區(qū)間數(shù)學(xué)的分析方法對車速、載質(zhì)量、道路坡度和滾阻系數(shù)等運(yùn)行參數(shù)的單一因素的波動(dòng)對純電動(dòng)公交車能耗的影響程度進(jìn)行分析,證實(shí)了純電動(dòng)公交車能耗隨運(yùn)行參數(shù)波動(dòng)產(chǎn)生變化的影響,進(jìn)而采用極差分析法從宏觀對相應(yīng)實(shí)際運(yùn)行參數(shù)進(jìn)行敏感性分析,其結(jié)果表明:道路阻力系數(shù)的波動(dòng)對純電動(dòng)公交車的能耗影響最大,能耗隨著承載質(zhì)量的增加而增大,而速度的波動(dòng)對公交車的能耗影響較小。
[Abstract]:It is a complex project to analyze the energy consumption economy of pure electric bus, and the actual operation parameters of pure electric bus are randomness and uncertainty in the actual operation process, so besides the type of driving motor, the parameters of battery, In addition to the influence of traditional factors, such as the matching degree of transmission system, on the energy consumption economy of pure electric vehicles, the speed and load quality of pure electric vehicles are analyzed by the method of interval mathematics. The influence degree of single factor such as road slope and rolling resistance coefficient on the energy consumption of pure electric bus is analyzed. It is proved that the energy consumption of pure electric bus varies with the fluctuation of operation parameters. Then the sensitivity analysis of the actual operation parameters is carried out by using the range analysis method. The results show that the fluctuation of the road resistance coefficient has the greatest influence on the energy consumption of the pure electric bus, and the energy consumption increases with the increase of the bearing mass. The fluctuation of speed has little effect on the energy consumption of buses.
