| 摘 要： | 为提高舰船的战斗力和生命力,研究水下爆炸载荷作用下典型舰船结构的损伤破坏模式以及构件爆炸变形能吸收特性乃是极其必要的。基于上述研究,并结合吸能理论,设计出4种吸能效果好、结构材料轻、制造工艺简单的舰船双层底新型防护结构形式;采用数值仿真与试验相结合的研究方法,分析新型结构形式的吸能效果,获得吸能效果较佳的舰船双层底新型防护结构形式。

| Abstract: | In order to improve the survivability and battle effectiveness of warships,typical structure damage types and characteristics of energy absorption by members of warship subjected to underwater explosion loading are investigated in this paper.And four kinds of new type double-bottom defensive structures,which have the excellence on energy absorption,material density and manufacture technology,are designed based on energy absorption theory.Finally the effectiveness of energy absorption for the new type structures is analyzed and compared with numerical simulation and experimental validation method.And a new type of doublebottom defensive structure which has the best effect for energy absorption is obtained. |
