Determination of the Effect of Various Parameters on Wear and Fatigue of Wire Rope Used in Navy Rigging Systems.
Abstract
The program was undertaken to help overcome the lack of general wire-rope design information by assessing the influence of various parameters common to the underway replenishment (UNREP) systems on the fatigue life of wire rope. The studies included analyses of the effects of single-sheave and multiple-sheave bends, reverse bends, sheave spacing, wire-rope core materials (IWRC, Sisal, Nylon, Polypropylene, and Dacron), and swivels. Both 1/2-inch and 3/4-inch diameter wire ropes were subjected to bending-fatigue experiments using sheave-to-rope diameter ratios of 15, 20, and 25 and factors of safety of 3, 5, and 8 based on actual measured rope breaking strength. Through these studies, information has been sought for improving UNREP equipment design and for developing preliminary wire-rope retirement criteria. (Author)
