车站到发线停车防溜器布置仿真研究

A Simulation Study on the Layout of Anti-running Device for Arrival and Departure Track

为提高到发线防溜作业效率和安全,可以在货物列车到发线布置停车防溜器,而到发线停车防溜器布置缺少设计依据,布置方案有效性难以保证。在分析到发线停车防溜器布置影响因素的基础上,研究单台停车防溜器独立布置、2台停车防溜器成组连续布置、3台停车防溜器成组连续布置方案可能存在的不利场景。针对停车防溜器布置方案的有效性难以直接计算的问题,设计开发到发线停车防溜器仿真模拟程序,计算典型车辆处在停车防溜器组覆盖范围内时停车防溜器的作用概率,根据机车停留位置和相关安全距离的要求,提出停车防溜器组布置位置方案,可以对既有车站布置方案进行检算。

To improve the efficiency and safety of railway anti-running operation, anti-running devices can be installed on the arrival and departure lines for freight trains. However, the effectiveness of the layout is difficult to achieve due to the lack of layout design. Based on an analysis of the factors influencing the layout of anti-running devices, this paper studies the possible unfavorable conditions for the layout of a single anti-running device, a two-anti-running-device group, and a three-anti-runningdevice group. To address the problems that may influence the layout effectiveness, this paper puts forward the simulation program of the anti-running device layout to calculate the effective probability of the anti-running device when the typical vehicle is in the coverage range of the device. According to the requirements of the locomotive’s stopping position and relative safety distance, this paper has proposed the layout plan of anti-running devices, which is expected to serve as a verification tool for the layout of the existing stations.
