摘要
文章以某一5米级龙骨帆船为基础设计方案,以外伸龙骨高度为主要变量,探索外伸龙骨高度对固有频率、静稳性、阻力、结构强度的影响。研究发现:1 m与2 m的外伸龙骨表现较好。文章的研究成果可为龙骨帆船的初步设计提供参考。
This paper takes a five-meter class keel yacht as the basic design scheme,and takes the extended keel height as the main variable.Explore the influence of the height of the extended keel on the natural frequency,static stability,resistance and structural strength.It is found that the extended keels of 1000 mm and 2000 mm perform better.The research results of this paper can provide reference for the preliminary design of keel sailboat.
