摘　　要：为解决现有船舶结构初步设计过程中精细化程度不足的问题,开展基于多工况拓扑优化算法的归一化数学模型研究及其典型应用探索。本文将多工况拓扑优化算法引入到船舶结构初步设计中,提出了基于k方法的权因子确定方法,引入全局化应力约束条件,建立考虑应力约束函数的多目标拓扑优化数学模型,并对某高双层底实肋板结构进行多工况静力学拓扑优化研究。结果表明,最终构型能够满足应力应变等基本约束条件且具备较好的工艺性。相关研究成果为运用拓扑优化方法进行船舶结构初步设计提供一条切实可行的途径,具有一定的理论与工程应用价值。In order to solve the lack of refined degree in ship structural preliminary design process at the moment,this paper carries out the research and application exploration of normalization mathematical model based on the topology optim-ization algorithm.Considering the multi-cases topology optimization algorithm applied on ship structural preliminary design process,put forward the weight factor computing method based on the k-method.By the global stress restrain,the multi-ob-jective topology optimization mathematical model involving the stress restrain function is established,and the research of multi-cases topology optimization of statics are conducted for the high plate floor design scheme.The results reveal that the final topology configuration of plate floor can satisfy the restrain conditions of the stress-strain,which has better manufactur-ability.The related achievements will provide a feasible way for ship structural preliminary design based on topology optim-ization method,which has normal academic significance and engineering application value.
