环向加筋圆柱壳轴向不均匀冲击响应

Dynamic Response to Ring-Stiffened Cylindrical Shells under Non-uniform and Impulsive Loading

对轴向不均匀冲击载荷下环向加筋圆柱壳的动力响应进行了研究．在考虑了壳体及加筋肋骨的剪切变形和转动惯性的情况下，运用Ｈａｍｉｌｔｏｎ原理推导出了壳体－肋骨系统的运动方程，并且采用一种半解析有限差分法进行求解．着重探讨了加筋肋骨对环向加筋圆柱壳动力响应的影响．

The dynamic response of ring-stiffened cylindrical shells under non-uniform and impulsive loading locally and axially is considered. The Hamilton variational principle is extended to derive the equations of motion, taking account of the shear deformation and the rotational inertia in the shells and the stiffeners. And a semi-analytic finite difference method is used to solve this problem. The ef- fects of the stiffeners on the dynamic response to ring-stiffened cylindrical shells is discussed.
