摘要
结合列车的运行状态,提出了基于节能以及优化相关工程条件的地铁线路纵断面设计方案,经分析表明:在牵引状态下,列车宜采用大坡度下坡以增加列车加速度,减少牵引距离及牵引能耗,同时使列车重力势能转换为列车动能;在制动状态下,宜采用大坡度上坡以增加列车制动力,减少制动能耗以及制动距离,同时使列车动能转换为重力势能。
Combining with the operation status of trains,the paper points out the design scheme for the longitudinal sections of subway routes based on the energy-saving and optimal engineering conditions,proves by the analysis that the large gradient slope can be adopted on trains under the traction so as to reduce the traction distance and energy consumption and replace the train's gravitational potential energy into train's kinetic energy,and indicates the large gradient ascent can be adopted under the braking status to increase the train's braking force,so as to reduce the braking energy consumption and braking distance,so as to replace the kinetic energy into the gravitational potential energy.
