Finite Element Analysis and Structure Optimum Design of Lifting Padeye

Abstract

The lifting padeyes are widely used in the offshore and shipbuilding industry. The design of lifting padeye requires extremely high safe reliability and economic rationality. Based on finite element analysis (FEA), the variations of stress and deformation with external force and hoist angle are analyzed. For minimizing cost of steel, optimum design models of lifting padeye were built and the reliability of the optimum design scheme was proved. The results show that the optimum design accords with structure design principle and the cost of padeye steel reduce notably.
