| Abstract: | The purpose of this paper is to explore the application of collaborative optimization(CO) methods to solve the optimization problems of ship structure with multiple damage models.Based on the basic theoretical framework of collaborative optimization method,the parallel design and optimization of the structure with multiple damage models are discussed,and the corresponding optimization model is established.Finally,structural static optimization with multiple damage model for ship structure is taken as an example,in which,the collaborative optimization is applied,and the best residual strength of structural damage is obtained through numerical simulation.Numerical results indicate that,the collaborative optimization method can effectively solve the structure optimization problem with multiple damage models. |
