城市轨道交通车辆选型的探析

目前国内绝大部分城市轨道交通速度目标值均为80 km/h,车辆的选型相对比较固定.V≥120 km/h的城市轨道交通在国内应用较少,可适用的车辆型式不仅有地铁模式,国铁动车组也是比较适合的方案之一,具体采用哪种模式需根据线路在线网中的衔接关系、设计速度目标值以及城市景观的影响等因素综合考虑.车辆选型不仅受运量控制,还受线路坡度、曲线半径、站间距等一系列因素影响,其对工程投资有着直接的影响.正确的选型对节约成本,提高运能,增加乘客的舒适度具有重要的意义.

Analysis of City Rail Transit Vehicle Selection

At present, most of the domestic city orbit traffic speed target value is 80 kin/h, and vehicle type is relatively fixed. V ≥ 120 km/h high speed city orbit traffic is rarely used in China, the feasible vehicle type includes not only sub-way mode but also the country＇ s EMU project. The specific system model should be chosen based on the comprehensive factors such as the railway network relations, design speed target and urban landscape and so on. Vehicle selection is not only affected by the volume control, but also affected by the slope of the line include curve radius, station spacing among other factors. It has a direct impact on the project investment. The correct selection of the vehicle could help cost savings, improve the transport capacity, and increase passenger comfort. Therefore, it is of significance.
