Abstract
Investigation of Optimum Helix Angle of a Wire Rope Subjected to Harmonic Dynamic Loading
Highlights
During the past some years, many developments have been carried out in the steadying the responses of metal cables that formed as spiral strands and wire ropes
Approximating methods were used for the dynamic analysis of the wire rope strand such as the finite element method, boundary element method in addition to the experimental techniques such as experimental modal analysis
The stress in upper location is the smallest while the stresses in middle location are larger than upper location and smaller than lower location, the stresses in core wire are less than stresses in the helical wire, for both core wire and helical wire, the helix angle (82 ̊) have the lowest stresses
Summary
During the past some years, many developments have been carried out in the steadying the responses of metal cables that formed as spiral strands and wire ropes. Jiang et al in [1] have been used finite element analysis of simple straight strand. Kastratović et al [2] have used advanced 3D modeling techniques and finite element method for wire rope strand analysis. N.F [3] have been studied using finite element analysis a realistic three dimensional structural model of a simple wire strand. Casey et al [4] have been investigated an introductory study into the ability to apply techniques of signal analysis to wire rope strand configurations. Wei-Xin Ren et al [6] have been carried out a validated study by using finite element method with respect to environmental vibration test results to be served as the base for a more accurate dynamic responses investigation. Finite element method is using to carry out this study such that two solutions including modal and frequency analysis are to be intended to reach to the objectives
