Modelling of dragline bucket for determination of stress

Abstract

Dragline is a substantial and costly machine. It is used in mining industries for removal of overburden, and the bucket is the crucial part of dragline which is applied for the removal of overburden. In this paper, an attempt has been made to analyze the stress analysis in a dragline bucket under the static condition using finite element method. For this purpose, a 3D robust model of the bucket has been developed with the help of auto cad and solid work. This 3D solid model was then imported into ANSYS 14.5 and analyzed under different loading condition. This study aims to find out the equivalent stress, damage, safety factor and fatigue life under static loading condition. Simulation results have highlighted those bucket hitch elements, and arc anchors have high-stress concentration and less safety factor. © 2017 AMSE Press. All rights reserved.
