Fatigue Life Analysis of Metallurgical Bridge Crane Structure

Abstract:

Crane runway girders are subject to cyclic loads, stress variation in the girders is a certainty. In this paper, Fatigue is investigated for the metallurgical bridge crane structure and an explanation of the concepts and design methods are provided. The fatigue test & analysis was carried out in the middle of girder bridge crane cover& its rail web, and the fatigue life of these Measuring points was calculated according to EN 1993-1-9:2005 Part 1-9, the result is consistent with the fatigue assessment result for bridge cranes Using MSC.Fatigue software ,which represents a strong practical significance.
