摘　　要：研究目的:随着地铁对节能要求和运营服务水平的提高,列车牵引能耗占总系统能耗的1/2,地铁线路纵断面坡度设计对列车牵引能耗影响尤为明显。本文通过研究各种最高速度(100 km/h、120 km/h、140 km/h)下市域快线节能坡的坡长与坡度,并分析V型坡与W型坡以及单面坡与多段坡运行能耗,最终得出经济适用的节能坡设置参数。研究结论:(1)节能坡设置长度:100 km/h为460 m,120 km/h为580 m,140 km/h为660 m;(2)长大区间下,结合适宜的站间距,W型坡较V型坡能耗更低,且随着缓坡坡度的增加,节能趋势更加显著;(3)两车站平均坡度大于10‰时,采用多段坡比采用单面坡能耗更低,且采用缓坡+陡坡的方案节能效率更加明显;(4)两车站平均坡度10‰~20‰时,随着单面坡平均坡度值的增加,多段坡节能效率逐渐降低;(5)本研究成果可为长大区间下市域快线线路纵断面设计提供参考。Research purposes:With the improvement of energy saving requirement and operation service level of metro,the traction energy consumption of trains accounts for one-second of the total system energy consumption.The influence of longitudinal slope design of metro lines on traction energy consumption of trains is particularly obvious.The paper studies the slope length and gradient of the energy-saving slope of urban express line at various maximum speeds(100 km/h,120 km/h and 140 km/h),and analyzes the energy consumption of"V"type slope and"W"type slope and single-side slope and multi-section slope under different maximum operating speeds.Finally,the economically applicable parameters of the energy saving slope are obtained.Research conclusions:(1)Set the energy saving slope length as follows:the length of the energy-saving slope at a train speed of 100 km/h is set to 460 m,120 km/h is set to 580 m and 140 km/h is set to 660 m.(2)In large interval,combining suitable station spacing,the energy consumption of"W"type slope is lower than that of"V"type slope,and the trend of energy saving is more significant with the increase of gentle slope.(3)When the average gradient of the two stations is higher than 10‰,the energy consumption of the multi-section slope is lower than that of the single-side slope,and the energy-saving efficiency of the scheme of gentle slope+steep slope is more obvious.(4)When the average gradient of the two stations is between 10‰to 20‰,the energy-saving efficiency of the multi-section slope decreases gradually with the increase of the average gradient of the single-side slope.(5)The research results can provide reference for the longitudinal section design of metropolitan rapid transit in large interval.
