Abstract: This paper introduces an analysis method of fatigue strength of the crane base bottom strengthening structure of the derrick barge. Taking a container derrick barge as an example, the stress level and stress amplitude of the strengthening structure for different slewing conditions are analyzed by finite element software. According to the its use frequency, the corresponding S-N curve is compared to verify whether it meets the use requirements.
Key words: Crane; Slewing; Finite element analysis; Fatigue strength; S-N curve
