摘要
将初缺陷放大准则应用于静力预加载环向加筋圆柱壳结构受轴向流 固冲击加载作用时的几何非线性动力屈曲研究中 .运用Galerkin方法推导出壳体 肋骨系统的动力屈曲控制方程 ,并且采用Runge Kutta法进行数值求解 .着重分析了静力预加载荷对结构屈曲性态及抗轴向冲击能力的影响 .
The initial imperfection amplified criterion is applied to investigate the geometric nonlinear dynamic buckling of statically preloaded ring stiffened cylindrical shells under axial fluid solid impact. The governing equations are obtained by Galerkin method and solved by Runge Kutta method. The effects of static preloading(radial external pressure) on the buckling features and the load carrying ability against axial impact of ring stiffened cylindrical shells are discussed.
