A Theoretical and Experimental Investigation of Snap Loads in Stranded Steel Cables

Abstract

During longitudinal oscillation of a cable with a payload supported at the lower end, a severe impact load called snap can be experienced if the cable should go slack. This report presents an analog model and a digital program for computing snap loads in cables during longitudinal oscillation simulating ocean wave motion. The theory is shown to agree well with experimental tests on stranded steel cable oscillated in water. Schemes for mitigating the snap load are discussed.
