摘　　要：传统的船底板一般采用纵横板架结构,但是随着船舶行业的快速发展,传统的板架结构已经无法满足新型舰船的设计制造要求。通过对增材制造技术的运用,在传统船底板纵横骨结构的基础上,根据仿生学原理,提出蜂窝底板结构,运用有限元分析的方法,对纵横骨结构与蜂窝船底板结构的屈曲强度和整体性能进行对比分析,验证了仿生学原理与增材制造技术相结合运用于船舶底板设计制造的可行性,在简化船体结构、船体结构轻量化、个性化生产及缩短制造周期等方面有应用前景,在传统板架结构的基础上,设计出新的蜂窝结构方案,并对其可行性进行初步研究,为今后进一步的研究打下理论基础。Based on the analysis about additive manufacturing technology, we come up with a cellular structure according to the principle of bionics, compared to the traditional manufacturing technology. The buckling with other overall performance between the traditional structure and cellular structure through the finite element analysis, which proves the feasibility on the combination of the bionics principle and the additive manufacturing technology,which applied to the shipbuilding industry. There are lots of application prospects in simplified and lighten the hull structures, and shorten the manufacturing cycle. It will be the theoretical foundation for the future research and has a big guiding significance.
