重载组合列车跳钩事故原因分析及改善建议
|
Abstract:
2万t重载组合列车担负着重载运输主力军的作用，但在列车运行过程中跳钩、脱轨事故时有发生，对列车的行车安全构成了极大威胁。近期，某重载线路上发生了一起2万t重载列车缓解后跳钩事故，使用列车空气制动与纵向动力学联合仿真系统对此次跳钩事故列车的运行过程进行了重现，分析了列车在缓解后发生跳钩的原因，并提出了针对性的改善方案，为重载组合列车提供了安全操纵方式借鉴。
The 20,000 t heavy haul combined train plays the main role of heavy haul transportation. But in the process of train operation, coupler separation and derailment accidents occur from time to time, threatening the security of train operation. A coupler separation accident of a 20,000 t heavy haul train occurred on a heavy-haul line recently. The accident process was reproduced by using the Train Air Brake and Longitudinal Dynamics Simulation System, and the cause of coupler separation of the train after release was analyzed. Improvement suggestions were proposed, providing a reference for the safe operation of heavy haul combined trains.
