摘要
研究目的:采用城市列车运行计算系统进行模拟仿真,统计不同列车在其上运行的能耗,通过对不同车型在同一组合上的牵引制动能耗进行分析,寻找每个线路组合对应的较优坡度取值范围,同时,分析同一车型在各线路组合间的牵引制动能耗,找出不同区间长度对应的较优区间组合,进而指导城市轨道交通线路节能设计。研究结论:本文充分考虑区间长度、列车车型、运行模式、限速等因素对计算结果的影响,通过模拟仿真运行,得出:(1)长度1 000 m的区间节能加减速坡取值范围为-18‰～-30‰;(2)长度1 200 m的区间节能加减速坡取值范围为-12‰～-30‰;(3)长度1 500 m的区间节能加减速坡取值范围为-12‰～-20‰;(4)随着加减节能坡坡长的缩短,后续坡坡长的增加,其牵引制动能耗消耗量将递减。
Research purposes： The computational system for the urban train operation was used for conducting the simulation to add up the energy consumptions of the different trains running on the slope. The the energy consumptions caused by the traction braking of the different types of train on the same combined slope were analyzed to find the value selection range of the optimal gradient corresponding to each track combination. Also the energy consumption caused by the traction braking of the same type of train on the each track combination was analyzed to find the optimal section combination corresponding to the different sectional lengths to direct the energy - saving design for the urban rail transit. Research conclusions： On consideration of the influences of the sectional length, train type, operation model and limiting speed on the calculation result, we can draw the following conclusions ： （ 1 ） In the 1 000 m long section, the value selection range for the optimal energy -saving acceleration or deceleration slope was from -18‰ to -30‰. （2）In the 1 200 m long section, the value selection range for the optimal energy - saving acceleration or deceleration slope was from - 12‰ to -30‰. （3） In the 1 500 m long section, the value selection range for the optimal energy -saving acceleration or deceleration slope was from - 12‰ to - 20‰. （4） Shortening the length of the energy- saving acceleration or deceleration slope and increasing the length of the follow- up slope, the energy consumption decreased progressively.
