Variation law of equivalent bending stiffness of steel-cored aluminum stranded wire under bending

Abstract

Steel core aluminum stranded wire, its abbreviation is ACSR, is a classic multi-stranded wire composed of different materials. Many scholars have used static experiments to study the mechanical properties of steel wire rope structures[1]. In this paper the author use the finite element software ANSYS to carry out numerical simulation on the aluminum-scored steel-cored wire of model LGJ/JL/G1A-300/25, gain a more in-depth understanding of the bending rigidity of the aluminum-steel wire the numerical change law and internal reasons of the bending stiffness of the wire structure.
