| Abstract: | In this paper, an integral lifting plan of whole ship is analyzed by the finite element method to make sure that the lifting will be safe. Ropes and pulleys are simulated precisely through constructing equivalent structure members. The finite element analysis results indicate that the equipment method is quite to the reality, equivalent structure members are in line with the mechanical characteristics of ropes and pulleys, and the plan of integral lifting satisfies the requirement of structural strength. |
