摘要：The lifting padeyes are widely used in the construction of offshore structures and ships. Because of the lack of more accurate information, heavily conservative simplified approaches have to be applied to strength analysis and structure design. Therefore, the calculated stress results contain a lot of discrepancies with the actual stress. In the paper, a robust stress check formula is derived using the theory of frictionless cylindrical contact. The influences of padeye thickness and clearance ratio on contact stress are analyzed. It is shown that the new expressions account for a better representation of the real stress value and distribution. By applying the strength check formula presented in the paper, the safe reliability of structure design can be improved significantly.
