Simulation Study on Braking Characteristics of 30,000 t Heavy Haul Train Configuration Scheme

摘要: 为探寻3万吨重载列车各种列车编组方式的优劣，利用TABLDSS仿真系统，仿真分析了1 + 108 + 1 + 108 + 1 + 108 + 可控列尾、1 + 108 + 1 + 108 + 1 + 108 + 1、1 + 162 + 1 + 162 + 1等3种编组形式下列车制动特性、制动后缓解特性、再充风能力。计算结果表明，以制动性能评价，性能由好至坏的编组顺序是1 + 108 + 1 + 108 + 1 + 108 + 1、1 + 108 + 1 + 108 + 1 + 108 + 可控列尾、1 + 162 + 1 + 162 + 1。以缓解同步性评价和再充风能力评价，1 + 108 + 1 + 108 + 1 + 108 + 1最好，1 + 162 + 1 + 162 + 1次之，1 + 108 + 1 + 108 + 1 + 108 + 可控列尾最差。由此得出3万吨列车最优编组方案是1 + 108 + 1 + 108 + 1 + 108 + 1，该工作为3万吨列车编组的选择提供参考。

Abstract: In order to explore the advantages and disadvantages of various train configuration modes of 30,000 t heavy haul trains, using the TABLDSS simulation system, the train braking characteristics, release characteristics and recharging capacity under the three configuration forms of 1 + 108 + 1 + 108 + 1 + 108 + controllable train tail, 1 + 108 + 1 + 108 + 1 + 108 + 1, 1 + 162 + 1 + 162 + 1 are simulated and analyzed. The calculation results show that the configuration sequence from good to bad is 1 + 108 + 1 + 108 + 1 + 108 + 1, 1 + 108 + 1 + 108 + 1 + 108 + controllable train tail and 1 + 162 + 1 + 162 + 1. According to the evaluation of release synchronization and recharging capacity, 1 + 108 + 1 + 108 + 1 + 108 + 1 is the best, followed by 1 + 162 + 1 + 162 + 1, and 1 + 108 + 1 + 108 + 1 + 108 + controllable tail is the worst, It is concluded that the optimal configuration scheme of 30,000 ton trains is 1 + 108 + 1 + 108 + 1 + 108 + 1. This work provides a reference for the selection of 30,000 t train configuration.
