Calculation Method for Heavy-Haul Train Rushing Across Slope and Its Application

摘要

摘要:为了研究重载列车动能闯坡性能,基于列车纵向动力学理论,充分考虑线路的平纵断面因素,建立了列车多质点分析模型.以列车坡顶速度不得小于机车的计算速度为评判准则,提出了列车动能闯坡的最低速度计算方法.针对重载列车扩编后遇到的动能闯坡实际工程问题,以某运煤专线计划增开万吨重载列车为例进行了动能闯坡最低速度的计算,计算结果表明:最低闯坡速度为72.80 km/h,坡顶最低速度为51.62 km/h,机车的计算速度为51.50 km/h,二者仅相差0.23%,说明该方法具有较高的计算精度.

Abstract:In order to investigate the uphill performance of heavy-haul trains, a multi-particle train model is built by the theory of train longitudinal dynamics, taking the plane and vertical sections of railway line into account. According to the principle that the train speed at the top of a slope should not be less than the calculation speed of locomotives, a calculation method of minimum speed is proposed for a heavy-haul train rushing across the slope. Then, taking a dedicated coal transportation line as an example, the method is applied to the problem of train rushing across a slope caused by the increase of train length in marshalling plan. The results show that the minimum speed of train rushing across the slope is 72.80 km/h. The running speed on the top of the slope and the calculated speed of the locomotive are 51.62 km/h and 51.50 km/h, respectively; and the difference between them is only 0.23%. This reflects the high precision of the proposed method.
