Fatigue Life Study of Hatch Corner on Large Bulk Carrier

摘要：

The fatigue life study of the hatch corner plays very important roles in design of hatch corner. The target function is the gravity of the hatch corner, and the constraint function is fatigue accumulation damage in the present paper. The structure optimal design theory has been combined with the fatigue life assessment method, to assess a hatch corner fatigue life of a large bulk carrier, and to optimize the hatch corner based on meeting the fatigue life. The hatch corner has been optimized under meeting yield strength and buckling strength. The numerical results show that the optimum method is fit to optimize the hatch corner.
