| 摘 要： | 利用MSC.Nastran软件对110m趸船在三种不同工况下进行有限元强度评估.在甲板结构不满足强度要求的情况下,对甲板结构提出三种加强方案,基于模糊综合评判理论,将船体强度、工艺性和经济性等因素作为评判参数,按成对比较法确定各参数的权重系数,构建满意度函数,对110m趸船甲板结构的三种加强方案进行模糊综合评判,确定出最优方案.

| Abstract: | The finite element analysis of 110m Pontoon is made by using MSC.Nastran software under the three load cases. Three reinforced schemes are put forward in the case of unsatisfied strength of the deck structure. Based on fuzzy comprehensive evaluation theory, the hull strength, manufacturability and economic factors are introduced as evaluation parameters. The coefficients of the parameters are determined according to the paired comparison and the satisfaction function is constructed. The fuzzy comprehensive evaluation of the three reinforced schemes of 110m pontoon deck structure is therefore conducted and the optimal scheme is selected. |
