悬挂式单轨列车进站稳定性控制设计探索与实践

Exploration and Practice of Station-entering Stability Control Design for Suspended Monorail Trains

  • 摘要:
    目的 目前,针对悬挂式单轨列车在进站稳定性控制方面的研究较少,为保证投入商业运营列车的进站稳定性和乘客上下车的安全性,有必要分析悬挂式单轨列车的进站稳定性控制设计。
    方法 以武汉光谷生态大走廊旅游配套设施-旅游专线一期工程为例,阐述了悬挂式单轨列车进站时的运动轨迹形态,分析了影响列车进站姿态的内在因素,并提出了控制列车进站稳定性的设计方法。基于车站导向轨的设计方案及试运行监测数据,综合分析了影响列车进站稳定性的相关因素。
    结果及结论 影响列车进站稳定性的内在因素为:进站时的列车运行速度、线路条件及列车自身结构;影响列车进站稳定性的外在因素为:载客量、是否偏载、风速及环境温度。结合线路条件,通过合理控制进站时的列车运行速度,能够提高列车进站稳定性。若无法避免列车与导向轨的碰撞,可考虑通过调整碰撞范围内的导向轨材质,减缓乘客乘坐时的不舒适感。

     

    Abstract:
    Objective Currently, researches on the station-entering stability control of suspended monorail trains are relatively limited. To ensure the train station-entering stability in commercial operation and the safety of passenger boarding-alighting, it is necessary to analyze the design for controlling the station-entering stability of the suspended monorail trains.
    Method Taking the tourism-supporting facilities-Phase I project of the tourism-dedicated line in Wuhan Optics Valley Ecological Corridor as an example, the motion trajectory of suspended monorail trains entering the station is elaborated, and the intrinsic factors affecting the train station-entering posture is analyzed, and design methods to control train station-entering stability are proposed. Based on the design scheme of station guide rails and trial operation monitoring data, the factors influencing the train station-entering stability are comprehensively analyzed.
    Result & Conclusion The intrinsic factors affecting train station-entering stability include the operating speed during entering the station, track conditions, and the train's inherent structure. While the extrinsic factors include passenger capacity, uneven loading, wind speed, and ambient temperature. Based on track conditions and by reasonably controlling the operating speed, the train station-entering stability can be improved. If collisions between the train and guide rails cannot be avoided, adjusting the material of the guide rails within the collision range can be considered to mitigate passenger ride discomfort.
