Fatigue life assessment of steel structures of a gantry crane
In this paper, non-destructive testing, finite element analysis, experimental stress analysis and cumulative damage theory were integrated into fatigue life assessment of steel structures of rubber tire container gantry crane. Ultrasonic testing (UT) was adopted to test thickness of steel structures in order to evaluate the corrosion situation; based on actual dimensions three dimensional finite element model was built to execute strength and stiffness analysis, and load spectrum of dangerous positions were extracted in a whole working cycle; wireless dynamic resistance strain gauges were applied in stress test in order to verify the precision of finite element analysis. Finally, based on S-N fatigue analysis theory, Miner rules was adopted to calculate total damage, and fatigue life of steel structures was predicted.
