English Abstract

The life of overhead travelling crane is usually determined by the fatigue life of welded box girder, the paper, therefore, studies the fatigue life of the test piece that is similar to the welded box girder of the overhead travelling crane, and then derives the logarithmic and exponential function expressions for the fatigue life under varied reliability R. It provides a reference for optimization calculation of the fatigue life of the main girder of the overhead travelling crane.
