| 摘 要： | 实验研究了舰船底部液舱双层板结构在水下爆炸作用下的动态响应问题。对舰船底部液舱模型在空载、半载和满载状态下进行了水下爆炸实验,测量了底部液舱外板和内板的壁压、加速度和动态应变等参数。在此基础上，分析了船体底部液舱外板和内板在水下爆炸作用下的响应特点，液舱满载时水下爆炸冲击波的透射作用和半载液舱飞溅载荷对内底的冲击作用等问题。

| Abstract: | A series of experiments were performed to research the dynamic response of fluid cabin at the bottom of warship subjected to underwater explosion.In these experiments,there are three states of fluid cabins,such as cabins without fluid,half fluid and full fluid.The wall pressure,acceleration and dynamic strain of the out and inner plates of these fluid cabins were obtained.Response mechanisms of the out and inner plates of fluid cabin subjected to underwater explosion were analyzed.Transmission effect of shock wave for cabin with full fluid and influences of splash load on inner plate of cabin with half fluid were discussed. |
