摘要
本文用能量法推导了具有纵横加肋圆柱壳的理论临界压力的计算公式,指出了深潜器圆柱壳宜采用横向加肋的结构形式,大直径新材料潜艇圆柱壳宜采用纵横加肋的结构形式,论证了大直径新材料潜艇圆柱壳采用纵横加肋的结构形式比只加横向肋骨但加大壳板厚度的结构形式优越,提出了制定纵横加肋圆柱壳的设计计算规则的建议。
In this paper the calculating formula of theoretical critical pressure with longitudinal and transverse-stiffened circular cylindrical shell is clerivecl with energy method. It is indicated that a circular cylindrical shell of container in large depth water should adopt transverse-stiffened structure type and a circular cylindrical shell of submarine with large diameter and new materials should adopt longitudinal and transverse-stiffened structure type. It is proved that, for circular cylindrical shell of submarine with large diameter and new materials, adopting longitudinal and transverse-stiffened structure type is better than adopting transverse-stiffened shell with larger thickness structure type. A suggestion for enacting a structural design and computation rule of the longitu dinal and transverse-stiffened circular cylindrical shell is presented.
