Abstract：The shunting operation of railway wagons is prone to heavy colision of the coupler，resulting in faults that affect train operation safety，such as the displacement of rear draft lug.This kind of fault is easily overlooked due to the limitations of relevant conditions during the technical inspection by TFDS.This paper examines in-depth the alteration in shape and the mutual position of related accessories after the rear draft lug is moved， proposing an efficient approach to identify the displacement fault of the rear draft lug of the wagon coupler.

Key words： railway wagon; dynamic operation; rear draft lug; displacement fault; judgment method

在铁路站场、专用线进行解编、调车作业时，若速度过快，列车纵向冲击能量容易超出货车缓冲器的容量，以及固定后从板座的铆钉承载能力，这种情况在现场俗称“重撞”。（剩余1942字）
