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

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.
