【 摘 要 】

Braided wire rope is vital for stringing conductors with tension in overhead transmission lines. Its structure and characteristics determine the safety and reliability of the stringing construction. Tensile loading is the main load-bearing form of the steel wire rope in this process. This study analyzes distributions of stress and deformation in braided wire rope subjected to tensile loading. A geometric model for YS9-8 × 19 braided wire rope was established, and the finite element simulation of the tensile process was carried out using explicit dynamics. The simulation results are analyzed to reveal the distribution laws of stress and deformation on whole rope and intermediate cross section.
