New Approaches for Model Generation and Analysis for Wire Rope
Independent wire rope cores are composed by helically wrapping a wire strand over a straight wire strand. Outer strand of the wire rope is composed with nested helical geometry which is difficult to model for analysis. In this paper a wire by wire based, a more realistic analysis model determination of an independent wire rope core is defined with the parametric equations of the nested helical geometry. The locations of the single and nested helical wires are created and the meshed model of each wire is constructed separately. Wire rope is assembled and the axial loading model is constructed and analyzed using finite element analysis. The obtained numerical results are compared with the theoretical results. The results have in good agreement and the wire by wire analysis gives insight about the wire loads acting within an independent wire rope core.
