Fatigue Life Analysis of Mine Hoist Drum

This article is based on a certain type of hoist drum, Moreover, we make the stress and mode analysis for the drum, and make preliminary check on it. Then find the position of the weak section, we calculate the force in each stage of hoisting system and draw force-timing load spectrum,we translate it into stress function of weak link. Based on above studies and conclusion, in line with the materials of the drum and Fatigue characteristic parameters and appropriate fatigue lifetime prediction model, we analysis the fatigue performance, in the end get the distribution of the drum’s fatigue life and the life of plane of weakness.
