上海机场联络线车辆选型分析

机场联络线是上海市域轨道交通线网中东西向的骨干线,起自虹桥枢纽,终于铁路上海东站,主线联通“两场两站”,旅行时间目标为将虹桥和浦东两大综合交通枢纽之间的运行时间控制在40 min内,以进一步整合航空、铁路等对外交通资源。结合上海机场联络线线路长度、车站分布及时间目标值要求进行分析比较,该线采用120~200 km/h速度目标值时其适应性较好。结合该线的功能定位、敷设方式、乘坐舒适度、时间目标值、车辆技术成熟度等多种因素综合考虑分析,推荐该线车辆采用AC 25 kV供电制式、设计速度为160 km/h的动车组。

Vehicle Selection for Shanghai Airport Con-tacting Line

Shanghai airport contacting line in is the E-W trunk line of suburban railway network.It starts from Hongqiao Transportation Hub,and ends at Shanghai East Railway Station,connecting two airports and two railway stations,targeting at the 40-minute goal of train travel time between Hongqiao and Pudong two transportation hubs,so as to further integrate resources of external transportation,such as aviation and railway.Based on an analysis of the line length,station distribution and time target of the contacting line,it is suggested that the maximum speed of the line between 120 km/h~200 km/h can be suitable.Through comprehensive consideration of various factors,such as the functional orientation,laying mode,time target of the line,and maturity of vehicle technology,the EMU vehicle is recommended to adopt AC 25 kV power supply mode with the design speed of 160 km/h.
