摘　　要：对模拟水面舰船结构的箱形梁模型在水下爆炸作用下的响应进行试验,借助高速摄像机观测气泡脉动过程和结构响应过程,发现箱形梁结构在水下爆炸作用下的响应可以分为三个阶段。不同的爆点位置,气泡脉动能够激起不同振动形式的鞭状响应运动。The experiment on the response of a box beam induced by underwater explosion was carried out. With a high speed camera, the bubble pulse and structural response were observed. It was found that the responses of box beam could be divided into three phases, which were shock phase, bubble pulse phase and damping phase. When the charge location was different, the vibration form of whipping will be different.
