Abstract： When anti-ship missiles penetrate into the ship armor, fragments and shock waves caused by explosion will severely destroy the personnel and equipment on the ships. In this study, three double-layer bulkheads with different interior sandwich structures were investigated, including X and hexagonal combined sandwich structure, cross-type honeycomb sandwich structure and cell growth type honeycomb sandwich structure. The penetration processes of three different bulkhead structures were simulated by software ANSYS/LS-DYNA. The simulation shows that the double-layer bulkhead with cross-type honeycomb sandwich structure is the most suitable. Finally, the dynamic response characteristics of the cross-type sandwich bulkhead structure are analyzed.
Key words： cross-type sandwich structure; forging fragments; dynamic response; ship armor; anti-ship missile

摘要:反舰导弹在侵彻进入舰艇装甲内部时， 爆炸产生冲击波和飞散破片对人员和舰艇内部设备具有严重毁坏性。 研究了三种不同内夹层结构形式的双层舱壁结构： X型与六边形组合夹层结构、 十字型蜂窝夹层结构以及细胞增长型蜂窝夹层结构。 采用ANSYSY/LS-DYAN模拟了自锻破片对三种不同舱壁结构的侵彻过程。 根据破片的速度衰减和靶板的能量变化可知， 十字型蜂窝夹层结构的双层舱壁结构最适合作为舱壁的中间结构， 并对其动态响应特性进行了分析。
