水下爆炸作用下潜艇冲击环境影响因素研究

潜艇结构在其生命周期内不可避免会遭受水下爆炸冲击载荷作用,水下爆炸载荷引起的潜艇板架结构冲击响应往往是引起舰载设备破坏的主要因素,为保证潜艇结构安全性和舰载设备正常使用,有必要对潜艇设备冲击环境进行深入研究。潜艇在水下爆炸载荷作用下冲击环境计算涉及到攻角、炸药类型、冲击因子、水深以及舰载设备安装位置等多方面因素影响。采用数值仿真方法,对影响潜艇设备冲击环境的多方面因素分别进行研究,为潜艇结构抗冲击设计提供参考。

Research on Influencing Factors of Shock Environment of Submarines Subjected to Underwater Explosion

Abstract: The ship structure is inevitably subjected to underwater explosion shock load during its life cycle. The shock response of the ship frame structure caused by the underwater explosion load is the main factor causing the damage of the shipboard equipment. In order to ensure the safety of ship structures and the regular service of shipboard equipment, it is necessary to conduct an in-depth study on the impact environment. Impact environment calculation involves many factors, such as the attack angle, the type of explosive, the impact factor, the depth of the water and the installation position of the shipboard equipment. In this paper, the numerical simulation method is used to study the various factors that affect the impact environment of ship equipment.
