摘要
文章基于鹅蛋的几何学特性设计了多蛋形交接耐压壳。多蛋形交接耐压壳中的各分段外形均与鹅蛋外轮廓一致,各分段的长/短轴、偏心距、厚度均相同,并通过环肋加强。文中对多蛋形交接耐压壳在受均布外压下的强度和屈曲特性进行了试验、数值和理论分析,并与单蛋形耐压壳对比。蛋形耐压壳比例模型的破坏实验结果显示:蛋形耐压壳的数值分析可以较好地预测真实破坏形式。
This paper describes a multi-segment egg-shaped pressure hull based on the geometric properties of goose eggs.Segments are connected with rib rings and made in the form of egg-shaped configuration.They have the same major axis,minor axis,eccentricity,and thickness.Results of numerical and analytical study into the strength and buckling behaviors of the multi-segment egg-shaped pressure hull under external pressure are discussed.An egg-shaped pressure hull fabricated in a single piece is compared.Collapsed tests of two nominally identical egg-shaped shells in laboratory scale are shown to verify the numerical approach used to study the post-buckling of pressure hulls.
