Analysis of Stress-Strain Distribution for Wire Rope of Traction Hoister

Abstract:

Besides the material properties and operating environment, the strain and strain state of the wires in multi-stage twisted rope with large frictional contact force, as applied in traction hoister of suspended access platform, strongly influence their service life. For an accurate quantitative prediction of the performance and a proper understanding of the underlying phenomena, a detailed analysis of the stress-strain distribution along all individual wires is required. For this, a numerical model for a wore rope in traction hoister was describe to be considering the complex strand pattern, mutual interaction by contacts form surrounding strands and contact deformation, in this paper. The model well understood response of wire rope under an axial tensile load and twisting moment, and concise described the effects of rope deformation on the rotate ratio and slip behavior of the hoister. The results of this model were compared with the experiment analyzed, which showed that the inclusion of interfacial forces at the contact locations and their associated effects of internal force of helical wires is importance.
