Abstract: Taking the laying process theory and the space geometric structure of wire rope into consideration, a geometric model of wire rope with self-rotating ratio has been described and a finite element model for calculating boundary condition has been presented. Then a program for the finite element modeling has been developed to create data files which can be transferred to ANSYS directly. Additionally, the stress and strain of wire rope formed in the once laying process and in secondary laying process have been analyzed. And the effect of self-rotating ratio on the forming stress and strain has been discussed.
Keywords: wire rope, geometric structure, laying process, self-rotating ratio, forming stress and strain.
