以双壳体潜艇的典型结构—双层环肋圆柱壳受多物体撞击为研究对象，开展了模型试验，并与仿真计算结果进行对比，验证了有限元数值仿真方法对求解该类问题的有效性。还从结构损伤变形、撞击力历程和能量转换等方面对多物体撞击壳体过程的动响应特性进行了分析。研究成果将为潜艇抗撞能力的评估及抗撞结构的设计提供参考。%Model tests of double ring-stiffened cylindrical shell, being as typical structure of double hull submarine, collided with multiple bodies are carried out and the applicability of numerical simulation technique to this problem is verified by a comparison with experimental result. Dynamic response characteristics are analyzed from the aspects of structural damage deformation, time history of collision and energy transformation. The study will provide certain basis and reference for the assessment and design of anti-collision structure of submarines.
