基于地铁A型车的模型,通过牵引计算从运 行时间、旅行速度、运行能耗等角度,研究不同线路条 件下80、100、120、140、160 km/h 等最高运行速度的运 营效果,得到不同线路条件下适宜采用的速度值。采 用无量纲化的综合评价方法,对具体线路最高运行速 度进行合理选择。以北京市规划建设的某条市域快线 最高运行速度的选择为例进行分析,表明北京市市域 快线140 km/h速度等级在理论上是比较合理的。

[Abstract]
Based on the model of metro A-type vehicle,authors of the paper studied the operational performance including operation time,traveling speed and energy consumption of regional express trains under five maximum running speeds ( 80 km/h,100 km/h,120 km/h,140 km/h,160 km/h) ,and obtained the reasonable speeds under different line conditions. Dimensionless method was adopted for the comprehensive evaluation. The simulation results for a planned regional express railway of Beijing indicated that 140 km/h is an appropriate maximum running speed.
