摘　　要：针对动车组相互救援时制动不同步导致的车钩强度不足的问题,以CR400BF救援CRH2A重联动车组为例,研究救援过程出现的恶劣工况“前拉后刹”和“前刹后顶”所产生的车钩力大小,以及当车钩强度不满足救援要求时,对动车组车辆进行制动力切除的探讨,并进行了实车验证试验。In view of the problem of insufficient coupler strength caused by unsynchronized braking during mutual rescue of EMUs,taking CR400BF to rescue CRH2A coupled muttiple units as an example,this paper studies the coupling force generated by the harsh working conditions of“front pulling and rear braking”and“front braking and rear pushing”in the rescue process,and discusses the release of braking when the coupler strength does not meet the rescue requirements,and conducts a verification test on real vehicle.

关 键 词：救援 前拉后刹 前刹后顶 制动力切除 试验
