摘 要:随着“一带一路”倡议的提出及非洲地区经济的不断发展,越来越多的城市轨道交通项目落地非洲。车辆作为城市轨道交通系统的重要组成部分,其选型是城市轨道交通项目建设中的关键一环。文章以西非某城市轨道交通项目为例,针对项目所在地电力供应匮乏但石油资源丰富的背景,通过分析城市轨道交通与干线铁路内燃动车组的差异,对车辆基本车型、编组方式、核心大部件等关键规格制式进行比对,结合本项目线路条件、运用环境及性能需求,最终选定以国内B型车为基础车型,采用鼓型铝合金车体并将车辆高度提升180 mm,由安装在拖车车底的内燃动力包提供动力,采用交-直-交流电传动方式牵引,编组形式为2动2拖的动力分散式内燃动车组。With the proposal of the"Belt and Road"initiative and the continuous economic development in Africa,more and more urban rail transit projects are being implemented in Africa.As an important part of urban rail transit system,vehicle selection is a key step in the construction of urban rail transit project.Taking an urban rail transit project in West Africa as an example,based on the background of the lack of electric power supply but rich in oil resources in the area,this paper analyzes the differences between urban rail and railway main line DMUs,compares the basic vehicle models,train formations,key parts and other key specifications and systems,combined with the line conditions,operation environment and performance requirements of the project.Finally,the Chinese B-type vehicle is selected as the basic model,the drum aluminum alloy car body is adopted,and the vehicle height is increased by 180 mm,powered by a diesel generator installed under the trailer cars.AC-DC-AC transmission mode is adopted for traction,and the train formation is 2-motor cars and 2-trailer cars diesel multiple units.
