大型舰船在水下接触爆炸下的毁伤与防护研究综述

大型舰船受到水中兵器的巨大威胁，尤其是在水下接触爆炸情况下，船体结构将产生严重的局部毁伤，给舰船的战斗力乃至生命力带来严峻挑战。本文以大型舰船水下防护结构为研究对象，简要概述了各国海军大型舰船水下防护结构形式的发展历程，分析了水下接触爆炸下的毁伤载荷以及对舷侧多舱防护结构的毁伤机理，总结了基于具体结构和不同毁伤元的防护措施；并针对目前的研究现状，提出了有待进一步研究的问题。以期为舰船的水下防护设计提供参考，从而提高我国大型舰船的结构抗毁伤能力

Review on the damage and protection of large naval warships subjected to underwater contact explosions

Large naval warships are severely threatened by underwater weapons. Especially, the hull structures will suffer excessive local damage in the case of underwater contact explosion, which brings severe challenges to the combat effectiveness and even vitality of ships. In this paper, the underwater protective structures of large naval warships were taken as the research object. The development history of underwater protective structures in various countries was briefly introduced. The damage loading generated by underwater contact explosion and the damage mechanism of underwater protective structures were analyzed. Based on the specific structures and different damage loading, the corresponding protective measures were summarized. In view of the present research situation, some problems were put forward for the future investigation. This may provide a reference for the design of underwater protective structures so as to improve the anti-explosion ability of large naval warships.
