水下爆炸冲击波载荷作用下舰船板架结构冲击可靠性研究

Study of ship plate frame structure reliability during underwater explosion shock

军舰和水下潜艇等军事作业平台,在执行任务时容易遭受水下炸弹、鱼雷等破坏性武器的袭击。其中,水下近距离、非接触爆炸可以产生能量很高的爆炸冲击波,对军舰和潜艇等产生巨大的破坏作用。因此,提高舰船板架结构的抗冲击波特性具有重要的意义。本文针对水下冲击波气泡脉动理论,系统研究舰船板架结构的水下爆炸冲击可靠性。

Military operations platforms such as warships and underwater submarines are vulnerable to underwater bombs, torpedoes and other destructive weapons while performing missions. Among them, underwater close range, non-contact explosion can produce high energy blast wave, warships and submarines and other tremendous damage. Therefore, it is of great significance to enhance the anti shock wave characteristics of ship frame structure. Based on the theory of underwater shock wave bubble pulsation, this paper systematically studies the reliability of underwater explosion impact of ship frame structure.
