摘要
将船体梁视为两端自由的 Timoshenko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二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 。
This paper describes 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 are considered. On the base of the two dimensional strip theory and the hydro elastic method, the whipping response of the ship induced by impulsive pressure is calculated, where the ship hull is treated as a free free Timoshenko beam. In addition, the anti shock performance of the floating raft vibration absorption machinery, which is acted by gas bubble impulsive pressure, is discussed.
