Abstract
As a new type of cable with excellent mechanical properties, the research on the mechanical properties of the locked coil wire rope is very scarce. Owing to its special section form and steel wire contact mode, the mechanical properties of the locked coil wire rope are significantly different from those of traditional cables. In this paper, based on the ABAQUS/Explicit platform, a refined modelling method of the locked coil wire rope is proposed considering real anchorage characteristics. The purpose is to study the mechanical properties, stress distribution, interface force conditions between steel wires, and failure process of the locked coil wire rope under axial load. Based on the Feyrer theory calculation method, the stress distribution law of steel wires in the tension process of the locked coil wire rope is studied, and its failure criterion is proposed. It is found that the steel wire stress distribution is uneven in the process of cable tension. The stress of the central steel wire is greater than that of the surrounding steel wires. Cable failure generally occurs at the end. The friction between the steel wires has little effect on the tensile process, but the quality of the anchorage end affects the ultimate strength of the cable.
