Structural Fatigue Analysis of a Container Crane

Abstract:

This paper presents an approach to evaluate the structural fatigue life of port cranes. Based on a testing of 40t/45m container crane in a port of China, the stress time-history collection, data processing, the determination of S-N curve and the distribution of the load amplitude is analyzed in detail. Finally, the modified linear cumulative damage law is employed to evaluate the remaining safety service life of the container crane. The result of this study can be a reference for the anti-fatigue structural design of cranes, and it also provides a guideline for ports’ management and maintenance departments to make maintenance plans for port cranes.
