城市轨道交通节能线路设计研究

摘要

在城市轨道交通中,能耗主要包括牵引能耗和动力能耗两部分,影响牵引能耗的因素主要包括车型、车辆启动和制动方式、车辆最高速度、线路条件、季节因素等.通过数据调查和牵引计算模拟,分析站间距、敷设方式、平曲线半径、节能坡的坡度与坡长、节能坡与站台端部的距离、节能坡组合方式等因素对列车牵引能耗的影响,提出节能线路设计的一般原则,并对节能坡的节能效果进行分析.%Energy consumption in urban rail transit consists of train traction, power and lighting. Factors affecting traction energy consumption include vehicle type, speed limit, conditions of line and seasonal climate. Through data investigation and train traction simulation, factors influencing traction energy consumption, such as station distance, laying mode, radius of horizontal curve, energy-saving slope gradient and length, distance between energy-saving slope and station and the combination of energy-saving slopes were analyzed, the basic principles for energy-saving route design were advanced, and the energy-saving effect of energy-saving slope was also elaborated.
