直线电机运载系统在首都机场线的应用效果及评价分析

直线电机运载系统在首都机场线已经成功运营,通过对直线电机运载系统的总体运营、全自动驾驶、车辆维护、轨道维护、牵引能耗及车辆国产化等情况进行调研与后评估,发现直线电机运载系统各项指标均达到当初设计目标,运营维护情况良好,归纳直线电机运载系统的优缺点。在后续直线电机线路设计中,借鉴相关运营经验,充分考虑运营维护的便利性和经济性,并将直线电机运载系统各子系统统筹考虑,如车—轨匹配、车—信号匹配等,达到全系统的最优。对于中运量、小半径曲线、大纵坡路段较多的线路,直线电机运载系统具备较好的适应性。为今后城市轨道交通中低运量线路规划与车辆选项提供相关经验,并为选用直线电机运载系统的线路设计与建设提供参考及优化建议。

Application Effect and Evaluation of a Linear Motor Carrier System on the Capital Airport Line

A linear motor delivery system (LMDS) was successfully operated on the Capital Airport Line. This study investigates and post-assesses the overall operation of the LMDS for fully automated driving, vehicle maintenance, track maintenance, traction energy consumption, and vehicle localization. It was found that all the parameters of the LMDS met the original design goals and that the operation and maintenance of the LMDS were in good condition. The advantages and disadvantages of the LMDS have been summarized in this study. The follow-up linear motor circuit design incorporated lessons learned from relevant operating experience, while fully considering the convenience and economy of operation and maintenance, and also factored in the various subsystems of the LMDS such as vehicle-rail matching, vehicle-signal matching, and to achieve system-wide optimization using the circuit design. For lines characterized by high traffic, small-radius curves, and large vertical sections, the LMDS exhibits good adaptability. This article provides information relevant to low-traffic route planning and vehicle selection for future urban rail transit, and also furnishes reference and optimization suggestions for the design and construction of the line used for LMDSs.
