INVESTIGATION OF TIE-DOWN EQUIPMENT USED ON A TRI-LEVEL AUTO CARRIER RAILROAD CAR
The forces developed in the tie-down equipment during normal running and coupling impact conditions were studied. The conclusions of this investigation are: chain force varies with car coupling impact speed; the forces recorded during the coupling impact and running conditions are the result of the weight of the automobile and its longitudinal and vertical acceleration; and maximum chain forces recorded during this particular field investigation are not necessarily the maximum forces that could ever be experienced under such operating conditions.
