Abstract

Wire ropes are extensively applied in civil engineering, mechanical and electrical applications. they are identified by several design, manufacturing and operating parameters. In this paper, we focus on the analysis and optimization of the effect of manufacturing parameters of wire ropes on the failure stress behavior of central core strands of 19x7 wire ropes. The central core strands tested are composed of 7 wires which are subjected to static tensile tests. Numerical simulations of the failure stress behavior of strands are realized using FEM calculation code. Moreover, the main results obtained are confronted with the experimental data. The aim is to identify the base material (E), the Winding angle θ) and the diameter (D) to obtain the target structure. To analyze and synthesize the effect of these parameters, a Variance Analysis (ANOVA) using Taguchi method is performed. The Taguchi L27 (3^3) orthogonal table is selected for this study.
