doi:10.3969/j.issn.1000-1093.2015.09.025

Abstract

Abstract: In order to reveal the failure of single-strand wire rope under impact load, the structural elastic-plastic attributes are analyzed by using the dimensional finite element model (FDM). According to the experiment data and wire structure, the parameters of the elastic-plastic model are determined, and a 3D FEM is established. Von Mises stress and plastic strain of the internal wire are deduced by calculating the static loading and impact loading. The results show that the Von Mises stress and plastic strain of the contact area are bigger than those of other areas, which is the main reason for the rope break.

Key words: solid mechanics, single-strand wire rope, impact loading, elastic-plastic analysis
