Abstract：In order to ensure the maximum payload of the suspended disc-shaped structures in the mid-dle of the ocean,it is necessary to study the lightweight design method.In this paper,we developed an optimization method for disc-shaped structures by using ANSYS finite element software and drawing on existing formulas related to the eggshell-shaped pressure hull.The results showed that the optimization of uniform-thickness disc-shaped structures could be directly calculated using the eggshell-shaped pres-sure hull formula.The optimization of variable-thickness disc-shaped structures could be carried out by using the response surface optimization method in ANSYS software.Compared with uniform-thickness disc-shaped structures,the lightweight achievements of variable-thickness disc-shaped structures were more obvious.
