1＋1编组2万t列车循环制动车钩力研究

Study on the Longitudinal Force of Cycle Braking of 20 kt Trains whose Configuration is Locomotive^10 kt-~Locomotived-10 kt

比较了大秦线不同编组重载列车循环制动过程中的实测车钩力，对1＋1编组2万t组合列车循环制动过程产生较大车钩力的原因进行了分析，并从机车操纵和优化列车编组方式以改善列车制动性能等方面提出了减小列车纵向力的优化方法。

This paper compares the actual longitudinal force of cycle braking of different configuration on Daqin railway line, and analyzes the reason which the 20kt trains whose configuration is locomotive--10kt＋loeomotive-10kt produced big longitudinal force when applied cycle braking, and put forward the optimization of reduce train longitudinal force from the locomotive manipulation and optimization of train formation to improve the train braking performance and other aspects.
