Experiment research of the dynamic response of fluid cabin in the bottom of warship subjected to underwater explosion

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.
