| 摘 要： | 通过研究在环肋圆柱壳的肋骨周向均匀布置肘板,得到肘板能有效限制肋骨的侧向变形,改善肋骨的侧向稳定性,提高肋骨的临界失稳压力,通过对比分析半肋距肘板和整肋距肘板,得到整肋距肘板对肋骨的侧向约束效果更明显,更有利于提高肋骨的侧向稳定性,最后得出整肋距肘板能有效提高肋骨的侧向稳定性和圆柱壳的整体稳定性。

| Abstract: | Through the research of bracket frame tripping, we can find that the bracket can effectively limit the lateral deformation of frame. What is more, the bracket can improve the lateral stability of frame and improve the critical buckling pressure of the frame. Based on comparative analysis from the half frame spacing bracket and the whole frame spacing bracket, the whole frame spacing bracket on the confinement effect is more obvious and is more conducive to improve the lateral stability of the frame. Finally it is pointed out that the whole frame spacing bracket effectively improve the frame tripping and the stability of ring stiffened cylindrical shell. |
