厦门BRT车辆升级改造关键技术研究

摘要

Xiamen BRT passenger flow is huge and the existing BRT vehicles could hardly meet the operational needs,which makes it urgent to conduct vehicle upgrade research.The tram selection program is determined based on the analysis of B-type cars,C-type cars,linear motors,trams in view of the impact on existing projects and operations.Of the two standard models of steel wheel rail and rubber tire guide commonly used in the tram,the rubber tire tram is recommended in BRT upgrade due to its advantages in minimum curve radius,maximum slope,running acceleration,emergency deceleration and small track bed thickness.The relevant research results can be applied to some of the existing road and bridge upgrade of rail transit project.%厦门BRT客流巨大,既有BRT车辆难以满足运营需求,迫切需要进行车辆升级改造研究.从对既有工程影响、对运营影响等方面对B型车、C型车、直线电机、有轨电车等制式进行分析比选,确定有轨电车选型方案.针对有轨电车中常用钢轮钢轨、胶轮导轨两种制式车型进行比选,胶轮导轨电车以最小曲线半径、最大坡度、运行加速度、紧急减速、道床厚度小等优点,推荐在BRT升级改造中使用.相关研究成果适用于部分既有道路及桥梁改造轨道交通工程.
