摘　　要：运用通用有限元分析软件ABAQUS分析某型水雷水下爆炸作用下的舰船结构动态响应,并得出以下重要结论:某型水雷水下爆炸产生的压力包括冲击波和多次气泡脉动压力,冲击波的能量主要作用在中高频,气泡膨胀产生的气泡脉动压力的能量以低频为主。水雷载荷作用下舰船结构响应具有局部性,舰船底部是冲击波载荷的主要承受者,其应力要比上层建筑大,而舰船底部最大应力则集中在中部迎爆面处。由于冲击波作用的区域比较大,舰船的艏部和艉部也受到了一定的冲击影响,但相对中部迎爆面处来说要小得多。In this paper, the commercial finite element program ABAQUS is used to analyze the warship＇s dynamic response under the effect of underwater explosion of torpedo, and the research shows that the pressure generating from underwater explosion of the torpedo includes shock wave whose energy works mainly on the middle and high frequency, and repeatedly bubble pulsating pressure whose energy works mainly on the low frequency. The warship shock response under the loading of torpedo is partial, and the stress on warship bottom is greater than that on the superstructure, whose greatest stress focuses on the middle place facing the explosion. Because of the relatively large area acted by the shock wave, though there is still certain shock effect acting on the bow and stem of warship, it is much lighter than what on the middle.
