铁路线路设置曲线限速对列车运行能耗影响分析

Analysis on the Influence of Curve Speed Limit on Train Operation Energy Consumption

基于列车运行功能转化方程,对铁路选线设计中设置小半径曲线引起限速时的列车运行能耗特点及列车减速距离对列车能耗的影响进行分析,得出限速对列车运行能耗影响的量化结果,以及减速、加速距离是影响限速条件下列车运行能耗的主要参数等结论,以期为铁路线路选线提供能耗影响参考,或应用于铁路建设项目线路方案选择的节能评价。

Based on the functional transformation equation of train operation,this paper analyzes the characteristics of train operation energy consumption when setting a small curve radius to cause speed limit in railway route selection design and the influence of train deceleration distance on train energy consumption,and puts forward the quantitative results of the influence of speed limit on train operation energy consumption,as well as the conclusion that deceleration and acceleration distance are the main parameters affecting train operation energy consumption under the condition of speed limit,so as to provide energy consumption impact reference for railway route selection,or to be applied to energy saving evaluation of railway construction project route scheme selection.
