As lifting points for ship block turning over and hoisting operation, the strength of the lifting eye directly affects the safety of the operation, therefore it is required for extreme high reliability. The conventional strength analysis can not exactly describe the actual stress and working conditions of the lifting eye, nonlinear contact and simplified finite element arithmetic are used for analyzing and checking the lifting eyes strength in this paper; and the stress force distribution formula, which can well reflect the true status of the pressure-bearing surface, is researched. Through the comparison of the various calculation methods, it can be found that the reasonable simplified method can approach the nonlinear contact finite element arithmetic with high precision and is characterized with higher calculation speed and more concise and practicable.
