移动闭塞下列车追踪运行研究

Research on Train Fleeting Operations with Movable Block

移动闭塞下列车的追踪运行有2种模式:撞"硬墙"模式和撞"软墙"模式。撞"硬墙"模式更加安全,而撞"软墙"模式更加高效。通过对2种追踪模式建模并对比分析,结合各自特点提出准撞"软墙"模式,对其进行建模分析,研究该模式下列车追踪间隔的计算方法,并通过Matlab仿真探讨该模式的性能。研究结果表明:选择合适的制动挡位,准撞"软墙"模式在保证安全性的前提下,其追踪性能优于撞"硬墙"模式,且稳定性和舒适性都优于撞"硬墙"模式。

There are two modes of train fleeting operations with movable block.One is"hard wall"hitting mode and the other is"soft wall"hitting mode.The former is safer while the latter is more efficient.Through the modeling and comparative analysis of the two modes,this paper proposes the quasi"soft wall"hitting mode based on characteristics of the two modes,and carries out modeling and analysis.It studies the calculation method of train headway in this mode,and discusses the performance of this mode through MATLAB simulation.The research result shows that if an appropriate brake gear is selected,the quasi"soft wall"hitting mode has better fleeting operation performance,stability,and comfortability than the"hard wall"hitting mode on the premise of ensuring safety.
