反舰导弹战斗部爆炸产生的高速破片会对舰船内部人员、武器设备等造成严重毁伤。为研究舰船防护结构的抗侵彻性能,在传统加筋板架舱壁结构的基础上提出一种双层平板舱壁结构,对高速破片侵彻薄板的理论和经验公式进行分析,验证计算方法的可行性;对两者在高速破片侵彻载荷作用下的失效特性、动态响应以及吸能情况进行比较分析,双层舱壁结构抗侵彻性能明显优于传统单层结构;对不同侵彻速度、不同舱壁板厚对双层舱壁结构性能的影响进行研究,和试验数据结果对比,计算结果与之相吻合,并给出舱壁结构吸能特性的影响参数,为双层舱壁结构进行优化设计提供参考。
The crew, weapons and equipment in the warship will be destroyed by high-speed fragments generated in the anti-ship missile warhead explosion. In order to analyze the anti-penetration performance of the protective structure, a kind of plate-connected double-layer transverse bulkhead was designed based on the traditional stiffened plate. The theoretical and empirical formulas for the penetration of high-speed fragments into thin plates were analyzed, and the feasibility of the calculation method was verified. The dynamical response and the energy absorption of the bulkhead structure under the penetration of high-speed fragment were investigated and the comparison showed that anti-penetration performance of double-layer structure is superior to the traditional single-layer stiffened plate . The influence of the penetration velocity and the thickness of the plate on the performance of the double-layer structure were studied to determine the main parameters. The calculated results are in good agreement with the relevant experimental data. The conclusions will provide reference for optimization design of double-layer bulkhead structure.
