摘要
移动闭塞条件下“闭塞分区”呈现出“移动”和“长度变化”的特征,其区间通过能力的计算较固定闭塞系统更加复杂。本文建立了移动闭塞系统区间通过能力的数学模型,对区间通过能力与列车追踪运行速度、跟驰车距和列车性能等参数之间的相互关系进行了定性、定量分析,并就关鍵参数的计算方法进行了深入的讨论,对移动闭塞条件下的列车运行控制与行车组织有一定的参考价值。
Under the control of moving block system,the block section features“moving”and“length changing”so that the calculation of carrying capability of the section is more complex than that of fixed block system.Therefore,a mathematic model is constructed to calculate the carrying capacity of the section under the control of moving block system.The relation of carrying capacity of the section and the parameters such as train follow-up speed,train follow-up distance and train perform ance,etc.,are analyzed qualitatively and quantitatively.In addition,the calculation method of key parameters is discussed in depth.The simulation shows that our study has certain reference for train control and traffic organization under the control of moving block system.
