重载列车低速缓解速度值探讨

针对目前规定的重载列车低速缓解速度值在实际执行中存在的问题,根据列车操纵实际、列车运行监控记录装置的有关数据,对重载列车常用制动后缓解时列车合力、运行速度的变化进行了分析研究。提出了两个新概念及计算方法:缓解列车制动时车辆全部缓解后应保持的最低速度及缓解时间。运用列车合力、速度和时间的关系公式,对重载列车最低缓解速度值进行了计算,进而提出了不同牵引吨数(辆数)重载列车最低缓解速度的取值建议。

Discussion on Low Release Speed of Heavy Haul Train

In view of the current low release speed of heavy haul in the actual implementation of the existing problems,according to the actual train control,train monitoring and recording devices on the data of heavy braking the train after train together at ease and speed of changes are analyzed.And the method of calculating the proposed two new concept vehicles are put forward:Mitigation Brake should maintain a minimum speed and release time.By using the relationship between speed and time formulas to ease the heavy train at a velocity calculation,then it presents some advice on how to set minimum realized value accoring to different traction tons and speed.
