| 摘 要： | 将船体梁视为两端自由的Ｔｉｍｏｓｉｈｅｎｋｏ梁，在借用二维切片法和水弹性方法的基础上，计算船体梁在水下爆炸于次脉动压力下的响应特性。同时，还建立了在考虑水面效应和气泡运动时舰船受到二次脉动压力的计算模型。最后，以实船计算为例，进一步分析了二次脉动压力下舰船振荡响应的特性。

| Abstract: | Underwater explosions generate gas bubble impulsive pressure.We described the calculating model of the gas bubble impulsive pressure,in which the effects of water surface and the up floating motion of the gas bubble were considered.On the basis of the two dimensional strip theory and the hydro-elastic method,the dynamic response of the ship induced by impulsive pressure was calculated,wherethe ship hull was treated as a free-free Timoshenko beam.In addition,the characteristics of the whipping response of a real ship subjected to the gas bubble impulsive pressure of underwater explosion was analysed. |
