摘要
虚拟重联是一种使列车以编队方式在轨道上追踪运行的技术,从而提高城市轨道交通运营的灵活性和提升线路的通过能力.本文围绕虚拟重联运行仿真和性能衡量,探讨了虚拟重联技术需要的安全制动模型,针对车站瓶颈区域提出了虚拟重联模型和车站追踪改进模型.通过数值计算和计算机仿真建模的方法,对提出的模型进行了仿真验算,结果表明:车站追踪改进模型与相对移动闭塞通过能力相当,虚拟重联模型通过能力最大;系统受到初始延误后,虚拟重联模型的延误恢复能力最强.
Virtual coupling is a technique that shall allow trains driving on the same track at a constant distance,thus providing the flexibility for subway operators to adapt to the changing traffic demands and to increase the capacity on today’s overloaded lines. In this paper,we focus on the simulation implement and performance measurement of virtual coupling,including the following aspects,the safety braking model required by virtual coupling technology is discussed. Virtual coupling model and improved station tracking model for the bottleneck area of the station are proposed. The numerical calculation and simulation analysis show that the passing ability of improved station tracking model and relative moving block is equivalent,and the virtual coupling model has the highest passing ability. After the initial delay of the system,the virtual coupling model has the strongest ability of delay recovery.
