摘要
[目的]为实现船体结构的轻量化设计,采用金属夹层结构代替传统的加筋板结构,在保证原有结构承载性能的前提下,降低船体结构重量。[方法]针对单轴压缩作用下V型和I型金属波纹夹层板的承载性能问题,利用ABAQUS软件,对其进行屈曲分析和非线性有限元分析,并与传统加筋板结构的承载性能进行对比分析,[结果]得到了金属夹层板的承载性能与失效模式。计算结果表明,结构型式不同使得其屈曲失效模式存在差异;相同重量下,设计的I型金属波纹夹层板承载能力最强,加筋板与V型金属波纹夹层板次之。[结论]不同结构型式的轻量化减重效率有所不同,金属夹层板的轻量化规律可为其在船体结构设计中的选型与应用提供参考。
[Objectives]In order to realize lightweight design of hull structure,the steel sandwich structure is used to replace the traditional stiffened structure to reduce the weight of hull structure on the premise of guaranteeing the load-bearing capacity of the original structure.[Methods]In view of the load-bearing capacity of type V and type I steel corrugated sandwich panels under uniaxial compression,the buckling analysis and nonlinear finite element analysis were carried out by using ABAQUS,and the load-bearing capacity and failure modes of steel sandwich panels were compared with those of traditional stiffened panels.[Results]The load-bearing capacity and failure modes of steel sandwich panels were obtained.The results show that the buckling failure modes of steel sandwich panels are different because of different structure types.Under the same weight,the designed type I steel corrugated sandwich panel has the highest bearing capacity,followed by stiffened panel and type V steel corrugated sandwich panel.[Conclusions]The lightweight efficiency is different for different structural types,the lightweight law of the steel corrugated sandwich panel can provide reference for the selection and application of similar panels in hull structure design.
