一旦一列火车在繁忙的铁路线上抛锚,就会影响整个交通网络。然而,在将救援机车挂接到受损列车上拖至下一站时,经常会出现联轴器脱位的情况,造成联轴器和驾驶室的损坏。为保证列车在联线过程中的安全运行,确定列车在不同线路条件下能否安全自动联线就变得至关重要。本文采用几何解析计算方法,计算了救援机车和断路列车在线路上的位置和位姿,确定了它们的联轴器的位置关系。然后提出了一个所谓的“耦合特征三角形”来确定列车是否可以安全自动地在铁路线上连接。所述三角形由车钩前端和车钩尾部的峰值点以及车钩上安全耦合区域的边线构成。通过判断三角形的形状,可以直接判断它们的耦合器是否能连接成功。该方法已应用于南昌城市轨道交通4号线列车耦合安全校核。结果表明:在半径为325 m的直线段,耦合器的最大摆角达到17.3957°;此时,耦合最为困难,需要通过牵引车手动连接列车;所有的计算结果都在实际生产线上得到了验证。通过比较不同的耦合安全性判断计算方法,表明本文方法准确、高效,用户可以更直观地判断耦合安全性。
Once a train breaks down on a busy railway line, it will affect the whole traffic network. However, when a rescue locomotive is hooked up to the broken train for towing it to the next station, it is common that coupling dislocation occurs, which results in damages to couplers and the driver’s cab. To ensure the safety of the trains during the coupling, it becomes crucial to determine whether they can be linked safely and automatically under different line conditions. In this paper, position and pose of the rescue locomotive and the broken train on the line are calculated by geometric analytical calculation method, which determines the position relation of their couplers. Then a so-called “coupling characteristic triangle” was proposed to determine whether trains can be safely and automatically linked on the railway line. The triangles are constructed by the peak points of the couplers head of the front vehicle and the rear one and border lines of secure coupling area on the couplers. By judging the shape of the triangle, it can directly judge whether their couplers can be connected successfully. The method has been applied to check the safety of the trains during coupling on the Nanchang urban railway Line 4. The results show that the maximum swing angle of the coupler reaches 17.3957° in the straight–curve section with a radius of 325 m. At this time, coupling is most difficult, and trains need to be connected manually through the tractor; all the calculation results are verified in the actual line. By comparing different calculation methods for judging coupling safety, it is shown that the method proposed in this paper is accurate, efficient, and users can judge coupling safety more intuitively.
