摘　　要：舰船的冲击环境研究是舰船抗爆炸抗冲击设计的基础。箱型梁作为新型甲板结构,势必会从结构形式和总布置2个方面改变舰船刚度和质量的分布,从而改变了舰船的冲击环境。本文通过数值仿真技术,建立箱型梁结构舰船水下爆炸模型,运用冲击响应谱分析方法对箱型梁舰船结构冲击环境进行研究,将箱型梁舰船冲击环境特性与母型船进行对比,并将箱型梁内外冲击环境特性进行描述,得出箱型梁-舰船冲击环境特性规律,对箱型梁舰船抗水下爆炸冲击设计有一定的参考意义。The research of naval ship shock environment of is the foundation of design of ship resistance to impact. Box-girder as a new deck form is bound to change the stiffness and quality from the structure and general arrangement, thus changes the ship shock environment. Through numerical simulation technology, the box-girder ship underwater explosion model is founded, the method of shock response spectrum analysis is used on the research of the ship shock environment, then the shock environment characteristics of the box-girder ship would be obtained,which is playing a guiding significance to the design of ship resistance to impact.
