肘板对肋骨侧向稳定性的影响
|
摘要
在环肋圆柱壳的肋骨周向均匀布置肘板,结果显示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;对比分析半肋距肘板与整肋距肘板发现,整肋距肘板对肋骨的侧向约束效果更佳,更有利于提高肋骨的侧向稳定性。研究结果显示,整肋距肘板能有效提高肋骨的侧向稳定性和环肋圆柱壳的总体稳定性。
Arranging the uniform layout of brackets around the frame of the ring stiffened cylindrical shell, the result shows that the brackets can effectively limit the lateral deformation of frame, and improve the lateral stability of frame with raising the critical buckling pressure of the frame. Comparing and analyzing the half and the whole frame spacing bracket, it is found that the whole frame spacing bracket on the confinement effect is more obvious and is more conducive to improve the lateral stability of the frame. The study result of the paper shows that the whole frame spacing bracket can effectively improve the frame tripping and the stability of ring stiffened cylindrical shell.
