摘　　要：以MSC/Dytran为平台,对浅层水中爆炸载荷作用下舰船结构的动态响应及设备冲击环境进行了研究。在对4种不同水底介质的浅层水中爆炸冲击波研究的基础上,模拟了偏恶劣的绝对刚性水底条件下浅层水中爆炸时某舰的动态响应,再以舰船主机为对象、以结构加速度响应为输入对舰船设备冲击环境作进一步分析,并以无限水深情况下的舰船响应和设备冲击环境为参照,对水底反射波的影响规律做了一些初步的探讨。The dynamic response of the warship as well as the shock environment of the equipment under the explosion in shallow water are investigated by means of the software MSC/Dytran. Based on the research on the shock wave caused by the explosion in shallow water with four kinds of water bottom, the ship＇ s dynamic response to the explosion with a rigid bottom is simulated. The shock environment of the ship＇ s engine room is analyzed by using the acceleration response of the ship structure. Some laws of the influence of the reflected bottom wave are summarized with the comparison of the ship＇ s response and the equipment＇ s shock environment under the explosion in infinite water.
