Abstract:

为研究两万吨列车在长大下坡道运行时缓解产生的较大车钩力问题，使用列车空气制动与纵向动力学联合仿真系统(TABLDSS)，分析主、从控机车电制动力的异步控制对缓解时最大车钩力的影响，并提出一种利用主、从控机车的异步控制来减小最大车钩力的优化方案。选取某重载铁路的两段路，优化前后结果表明：第一段路列车的最大拉钩力降低8.2%；最大压钩力降低52.3%；第二段路列车的最大拉钩力降低12.1%，最大压钩力降低49.9%。说明缓解时增加主控机车的电制动力，减小从控机车的电制动力，可以减小列车所受到的最大拉钩力；出现最大拉钩力后10 s内降低主、从控机车电制动力可以减小列车所受到的最大压钩力。
To study the overlarge coupler force of the 20000-ton heavy haul train when it was releasing on a long steep ramp during the operational process, by using the Train Air Brake and Longitudinal Dynamics Simulation System (TABLDSS), when the train is releasing, the asynchronous control of main and slave locomotive is analyzed, and an optimum operation method is proposed. Two parts of a heavy haul line examples results show that the maximum tensile coupler forcer reduces by 8.2% and the maximum compressive coupler force reduces by 52.3% on the first heavy haul line and the maximum tensile coupler force reduces by 12.1% and the maximum compressive coupler force reduces by 49.9% on the second heavy haul line. It is proved that operation method of increasing the electric braking force of the main locomotive and reducing the electric braking force of the slave control locomotive can decrease the maximum tensile coupler force of the train and reducing the electric braking force of the main and slave locomotive can decrease the maximum compressive coupler force in 10 s after the maximum tensile coupler force occurs.
