摘要
研究目的:合理的中低速磁浮交通系统疏散救援设计是其运营安全保障的关键。针对国内磁浮运营线疏散演练效率偏低的现状,结合其疏散平台设计方案,提取与平台疏散能力相关的中低速磁浮列车和疏散平台的关键特征,建立中低速磁浮交通系统的Pathfinder疏散仿真模型,开展疏散平台优化研究。研究结论:(1)当前中低速磁浮交通系统区间疏散平台疏散总用时近30 min,疏散能力还存在优化空间;(2)疏散平台栏杆间隔、疏散平台有效通行宽度和桥梁下桥点位置等参数是影响疏散能力的关键参数;(3)通过优化各参数取值,提出疏散平台设计新方案,新方案可大幅提高中低速磁浮交通系统的疏散能力,疏散总用时可降低约44%;(4)本文提出的疏散平台优化思路及方案可为后期中低速、中速磁浮交通系统的疏散平台设计和运营维护提供数据支撑。
Research purposes: Reasonable evacuation and rescue design of mid-low speed maglev transportation system is the key to its operation safety. Aimed at the status quo of low evacuation efficiency in the evacuation drill held in the existing mid-low maglev operation line,this paper combines with the evacuation platform design and extracts key characteristics of mid-low speed maglev train and evacuation platform,which is related to the evacuation ability of the platform,and establishes a Pathfinder evacuation simulation model to optimize the evacuation platform.Research conclusions:( 1) It takes nearly 30 min to complete evacuation of all passengers. There is still potential for improvement in evacuation capacity.( 2) Some design parameters,such as the handrail spacing,width of the evacuation platform,location of bridge evacuation,are the key data to affect the ability of the evacuation.( 3) A new design scheme of evacuation platform is proposed by optimizing the parameters. The new scheme can greatly improve the evacuation capacity of mid-low speed maglev transportation system,and reduce the total time of evacuation by about 44%.( 4) The optimal thinking and new scheme of evacuation platform proposed in this paper can provide data support for the design and operation and maintenance of evacuation platform of mid-low speed and medium-speed maglev transportation system.
