多层防护结构舱内爆炸试验

舰船舷侧多层防护结构的主要作用是抵御反舰武器对内部结构的破坏。文章通过反舰武器战斗部模型在舰船舷侧防护结构内部爆炸的模拟试验,研究了战斗部内爆作用下防护结构的破坏模式、多层防护结构防御冲击波和高速破片的效果以及内部结构的冲击响应,对比分析了空舱和水舱在战斗部接近爆炸作用下的变形和破坏情况。通过对试验数据的分析发现在战斗部接近爆炸载荷作用下,水舱内板的动态响应出现了"二次加载"现象。

Experiment of a multi-layer protective structure under an inner explosion

The main function of the multi-layer protective structure of a warship is to prevent the inner cabin from being destroyed by the anti-ship weapons.In this paper,through an experimental test where the model of an anti-ship weapon's warhead explodes within the protection structures of a ship,the failure patterns of the protection structures under the explosion of warhead,the protection effect of the composite multi-layer structures from shock wave and high velocity fragments and the shock responses of the inner structures are investigated.Through the analysis of the test data,it is found that the fluid pressure in the liquid cabin oscillates and that the dynamic response of the inner panel of the water tank indicates the secondary loading phenomenon.
