摘要

重载组合列车在长大下坡路段制动缓解时常常出现较大的车钩力，严重时会导致脱轨、断钩事故，威胁到行车安全。使用空气制动与纵向动力学联合仿真系统，计算了“神8＋神8”，“神8＋神12”与“神12＋神8”三种列车编组在长大坡道制动缓解工况中不同的再生制动力分布对列车纵向冲动的影响。计算结果表明，在总再生制动力相同情况下，神12作为主控机车时缓解后最大拉钩力比神8＋神8编组平均减小了12.6%，提出了车钩力降低的发生机理，长大坡道缓解时大再生制动力机车作为主控机车较为合理，为重载组合列车差异化控制提供了基础。

Abstract

The excessive coupler force often occurs when a heavy haul combined train is releasing on a long steep ramp, and the overlarge coupler force may cause derailment and coupler fracture, threatening the security of train operation. Using the Train Air Brake and Longitudinal Dynamics Simulation System (TABLDSS), Influences of different locomotive regenerative braking force distribution of “S8+S8”, “S8+S12”and “S12+S8” train marshalling on longitudinal impulse during braking and releasing process was simulated. The results showed that, under the same total regenerative braking force, the maximum tensile coupler force of “S12+S8” marshalling could be reduced by 12.6% than “S8+S8” marshalling; a mechanism of reducing coupler force was proposed; it’s reasonable for reducing the tensile coupler force that a high-powered locomotive acts as main control locomotive during a train is releasing on a long steep ramp, providing the foundation for heavy haul combined trains’ differentiated control.
