摘要

文章根据纵向动力学理论，建立2万t重载列车纵向动力学仿真模型，研究车辆数量对列车纵向冲动的影响，给出长、短编组混编建议。同时，基于同步减少前后部车辆数量、仅减少前部车辆数量与仅减少后部车辆数量等3 种情况（后2种情况可视为长、短编组混编），计算列车空气制动延时、缓解延时和循环制动工况下的最大车钩力。结果表明：对于“ 1+ 1+可控列尾”编组形式的2万t重载列车，同步减少前后部车辆数量可有效降低列车缓解过程中的缓解延时和最大车钩力；当仅减少前部列车车辆数量时，最大缓解延时变化较小，无法有效降低纵向冲动；而减少后部列车车辆数量可有效降低最大缓解延时，对减小纵向冲动具有十分显著的效果，对重载列车编组优化有一定指导意义。因此，对于长、短编组混编情况，将短编组编至长编组后可有效降低列车运行的纵向冲动。

Abstract

This paper analyzed the effect of train quantity on the train longitudinal impulse experienced

by establishing a longitudinal dynamics simulation model of the 20 000-ton heavy-haul trains on the theory of longitudinal dynamics and offers recommendations for mixed marshaling of long and short consists. Moreover

this study included calculations on delays in air braking application and release

as well as the maximum coupler force in cycle braking conditions under three scenarios: synchronous reduction of front and rear wagons

reduction of only front wagons

and reduction of only rear wagons. The latter two scenarios represent mixed marshaling of long and short consists. The results reveal the following findings for 20 000-ton heavy-haul trains in a “1+1+controllable train tail” formation. Synchronous reduction in front and rear wagons effectively mitigates release delay and maximum coupler force during the release process. Reduction of only front wagons results in a small change in the maximum release delay and fails to sufficiently reduce longitudinal impulse. Conversely

reduction of only rear wagons considerably diminishes the maximum release delay and significantly mitigates longitudinal impulse. These findings offer valuable guidance for optimizing heavy-haul train formations. Therefore

for mixed marshaling of both long and short consists

coupling a short consist at the rear of a long one is an effective solution to reduce longitudinal impulse during train operation.
