Rail Transit Platform Screen Door Design in Flexible Marshalling Operation Scenarios

Objective In the context of green-smart integration, flexibly marshalled trains require PSD（platform screen door） systems to be compatible due to marshalling variations. Aiming at the difference in the position of passenger compartment doors between reconnected short-and long-marshalling trains, it is necessary to optimize PSD structure, control system and interface solution design for safe and efficient boarding/alighting of passengers in the flexible marshalling mode, achieving dynamic matching of passenger flow, capacity and energy consumption. Method Taken the matching problem of PSD facilities under flexible marshalling operation scenario as the research object, based on the position and parameter characteristics of train passenger compartment doors under such scenarios, four typical compatible PSD schemes and interface design principles are proposed. The PSD operation characteristics under flexible marshalling operation scenario are analyzed, and the structural safety of compatible PSD is analyzed based on the finite element analysis method. Result ＆ Conclusion In scenarios of flexible marshalling and different trains arriving at the station, the established compatible PSD system can effectively address the compatibility challenges posed by different trains in flexible marshalling operational scenarios.
