Research on opening coupling topology optimization of cruise ship structures
In view of the fact that traditional BESO algorithms cannot only optimize openings,we take the longi-tudinal truss,hull side,and through hole structures of cruise ship decks as the research object,and improve the BESO algorithm to obtain the I-BESO algorithm suitable for optimizing the opening hole types of ship hulls under multiple working conditions.Iterative optimization of hole types and analysis of multi type hole coupling optimiza-tion under multiple operating conditions are carried out.The reduction ratio of the opening volume reaches 20.92%,meeting the lightweight design goal and alleviating stress concentration,so as to achieve a balanced distri-bution of structural stress.
