舰船结构舱内爆炸毁伤与防护研究进展

Review of the damage and protection of warship structures under internal blast loading

舰艇是海军赖以生存和打击敌军的平台,也是发生海上战争时敌军的主要攻击对象.反舰导弹是舰艇面临的主要威胁之一,其主要攻击模式是侵彻舰船甲板或舷侧外板进入舰船内部发生爆炸.本文将舰船结构舱内爆炸毁伤与防护研究分为载荷特性、结构响应和防护技术三个方面,分别论述了其研究进展.首先介绍了舱内爆炸的载荷特性,其次分析了舰船结构的毁伤效应,然后总结了防护技术的研究现状,最后对未来的研究工作提出一些建议.

Warships are naval platforms to launch and survive attacks, and they are the main target of the enemy in a sea war.Antiship missiles are one of the main threats to warships. The main attack mode of an antiship missile is to penetrate into the ship deck or side plate and explode inside the cabin. The main damaging elements of an internal blast loading through a warhead include shock wave and quasistatic pressures and high-speed fragments. All the damaging elements are coupled, resulting in a serious damage to the warship structure. Therefore, research on warship defense technology is particularly important to improve the ability of warships to resist impact damage and enhance the vitality of warships. In this paper, advances in research on the explosion damage and protection of ship structures in cabins are systematically discussed. Moreover, the load characteristics of an explosion in the cabin and damaging effects to the ship structure are introduced, and the status of defense technology research is summarized. Finally, some suggestions for future research are proposed.
