| 摘 要： | 采用有限元方法计算了加筋板在流固冲击下的动态稳定性,研究的目的是对舱壁结构受水下爆炸冲击时的动态稳定性提供参考和依据.详细分析了影响加筋结构动态屈曲的各种因素:加筋与筋的厚度、初始几何缺陷的形式与大小、冲击载荷的脉宽和幅值、边界条件、筋的分布以及板的厚度.在分析研究的基础上提出了改善加筋板抗失稳的方法,以利于工程设计中具体应用.

| Abstract: | Dynamic stability of the stiffened plates subjected to solid-fluid impact is calculated with finite element method.That is helpful for the dynamic stability of the bulkheads in underwater explosion.Some factors are analyzed,including stiffened plates and the thickness of the stiffened plates,the magnitude and the shape of the initial imperfection,the impact pulse width,the pulse load,the edge conditions,the distributions of the stiffeners and the thickness of the plate.Some suggestions are presented accordi... |
