Experimental Research on the Dynamic Characteristics of Wire Rope Transverse Shock Wave

Due to their high strength and good flexibility, wire ropes are widely used in various intense applications. A wire rope will present complex wave mechanics, especially under impact conditions. In this article, wire ropes (steel core rope and hemp core rope alternately twisted) were used to study the wave dynamic response of steel wire ropes with preload shock. The transmission law of wire rope shock waves was obtained through actual measurements. The results showed that the compression wave and shear wave were generated and propagated along the rope after impact. The conduction of shear waves had significant reflection characteristics, and the reflected waves overlapped with each other. The conduction velocity of the impact shear wave of the steel core wire rope increased with increasing pretension. The peak tension caused by impact decayed exponentially. However, the half attenuation period of the amplitude of the hemp core wire rope after impact was longer, and the change in conduction velocity was more linear with increasing pretension. These findings show that the hemp core wire rope has good impact resistance.
