摘要

摘要: 随着聚能战斗部在水中兵器的广泛应用, 开展防护材料的抗冲击抗侵彻性能研究具有重要意义。文中利用 AUTODYN 有限元软件建立聚能装药水下爆炸模型, 对聚脲防护材料的抗冲击抗侵彻性能展开研究。根据面密度理论, 讨论了聚脲涂层处于不同位置时的防护效果, 对破口、挠度、吸能和降速等结果进行对比分析, 给出了聚脲涂层的最优涂敷位置。在此基础上, 对钢板/聚脲/钢板复合结构进行优化, 结果表明：聚脲复合结构的防护效果并没有随着聚脲涂层厚度的增加而提高, 通过对比分析给出了钢板/聚脲/钢板的最佳比例为 2/10/2。文中研究可为舰船防护设计提供理论依据和数值支撑。

Abstract: With the widespread use of shaped-charge warheads in underwater weapons, it is of great significance to study the anti-explosion and anti-penetration performance of modern warships. In this study, an underwater explosion model was developed using the AUTODYN finite element software to study the anti-explosion and anti-penetration performance of polyurea protection materials. The protective effects of polyurea coatings in different positions are discussed according to the surface density theory. The results for crevasse, deflection, energy absorption, and velocity reduction characteristics are analyzed comparatively. The optimal position of a polyurea coating is determined to be inside a sandwich of steel plate-polyurea-steel plate. This type of composite structure is optimized. The results demonstrate that with an increase in the thickness of polyuria, its protective effects do not improve and the optimal ratio of steel plate-polyurea-steel plate is 2:10:2. These results provide a theoretical basis and numerical support for ship protection design.
