中文摘要： 本申请针对NSAF联合基金“重点支持项目”的课题F3考虑船体结构的水中爆炸流固耦合研究提出。现代水中兵器对潜艇、舰船的毁伤主要通过近场爆炸产生的强冲击波载荷作用。而目前对近场强载荷传播衰减特性以及强载荷与潜艇、舰船结构的流固耦合作用机理研究较少。本项目拟通过对炸药水中爆炸近场冲击波载荷传播衰减规律研究和国内外典型舰船结构特性研究，建立典型潜艇、船体结构特征的分析方法和考虑边界条件的水中爆炸载荷分布计算方法。在此基础上，建立水中爆炸近冲击波与典型潜艇、舰船结构相互作用产生的应力波耦合规律，水中爆炸能量与潜艇、舰船结构的耦合模型和计算方法。

英文摘要： This application is proposed for Subject F3, Study of Fluid-Structure Interaction in Underwater Explosions with Hull Structures, of “Key Project” of the NSAF Joint Fund. The damage of modern underwater weapons on warships and submarines is caused mainly by the strong shock wave load in near-field explosions. To the present, studies have been rarely conducted on the attenuation characteristics in the propagation of near-field strong shock wave load and the mechanism of fluid-structure interactions between the load and structures of ships and submarines. The project intends to establish an analysis method of structure characteristics of ships and submarines and calculation procedures for underwater explosion load distribution considering boundary conditions through investigations into the propagation attenuation of shock wave load in underwater explosions and studies on typical ship structures. On this basis, calculation methods are to be established for the propagation of stress waves in the interactions of near-field underwater explosion shock wave and typical ship and submarine structures; coupling models are to be proposed for underwater explosion energy and structures of ships and submarines.
