Fatigue Life Assessment of Steel Structures of a Metallurgy Crane

Abstract:

A fatigue life assessment method of steel structures was proposed in this study and applied in a metallurgy crane. Analytical method and experimental analysis were adopted to evaluate the static strength of steel structures, and then dynamic stress test was applied to get the stress history in a whole working cycle, which could determine the interest point and stress spectrum. Finally, rainflow method was applied to approach the stress spectrum, and then the fatigue life was predicted based on Miner rules. The results indicated that this method showed a potential application in practical engineering.
