肋骨侧向失稳的非线性屈曲分析
Nonlinear Buckling Analysis of Frame Tripping
摘要
Abstract
Ringstiffened cylindrical shell is a kind of typical pressure vessel and usually we arranged ring frames along the circumferential direction to improve the stability.Along with that the deep water pressure increases gradually,the possibility of frame tripping is increased,thereby affecting the overall stability of the ring stiffened cylindrical shell.The finite element method of nonlinear buckling analysis was carried out on ring stiffened cylindrical shell to get thesequence of the shell plate and frame deformation and the node stress with the change of load.Through comparative analysis,we got the limit bearing capacity of ring stiffened cylindrical shell on initial geometric imperfection and the destruction mechanism of frame tripping,so as to provide reference for engineering design.关键词
