水下爆炸作用下船舱浮筏系统的冲击响应试验研究

设计了船舱浮筏系统的水下爆炸试验装置，测试了浅水域中爆炸的水下爆炸载荷，分析了存在结构反射时的冲击波和气泡脉动压力的幅值、比冲量和能量密度，指出以低频成分为主的气泡脉动压力，对舰船设备隔离系统的冲击响应产生重要的作用。并对水下爆炸载荷作用下船舱浮筏系统的冲击响应进行分析，其结果对于研究舰船设备的抗冲击性能具有参考价值。

Experiment Study on Shock Response of Ship Cabin with Floating Raft System Subjected to Underwater Explosion

An experiment installation of ship cabin with the floating raft system subjected to underwater explosion Was designed. The load of underwater explosion in shallow water was measured. The amplitude, the ratio impulse and the energy density of the shock wave as well as the air bubble pressure with structural reflection are analyzed. It is pointed out that the load of air bubble pressure made up of low frequency component is important to the shock response of the marine equipment isolation system. The shock response of the ship cabin with the floating raft system subjected to underwater explosion is analyzed. The results are practical to study the anti-shock property of the marine equipment.
