Wire Strand with Complex Shaped Elliptic Outer Wires
The main advantage of wire ropes is their ability to operate under high tensile load and in this way to resist large axial loads. Different types of wire ropes are produced according to increase their strength over the traditional ones. For example compacted wire ropes are low stretch wire rigging which increase the breaking strength and stretch of the wire ropes compared to the traditional wire ropes. Outer wires are formed using a special process called compacting. In this article, a three-dimensional model of different external wire cross-section is examined. For this purpose, a (1+6) wire strand model designed by using elliptical cross-sectional outer wires are designed. Then finite element analysis results for stress, displacement and contact pressure are presented.
