Modeling and Analysis of the Rope–Sheave Interaction at Traction Interface

Abstract

In this paper, a three-dimensional (3D) finite-element (FE) contact model of a 6 + 1 wire rope strand bent over a simplified traction sheave is developed to investigate the traction behavior at the interface. The stress as well as the tension distribution within the 6 + 1 wire rope are discussed first. The FE analysis indicates that ascending preload at rope-ends leads to the incensement of the real contact wrap angle, which is critical in the calculation of traction capability. Meanwhile, the influences of groove angle on the contact pressure distribution and traction capability are demonstrated as well.
