舰船在水下爆炸气泡脉动压力作用下将产生鞭状运动冲击响应。
The whipping response of a warship subjected to an underwater explosion usually is agitated by the bubble impulse after the explosion shock.
应用数值模拟方法对水下爆炸产生的诸如气泡脉动规律、脉动周期、水中冲击波压力的变化等特性进行了研究。
The characteristics of underwater explosions such as pulsation law and pulsation cycle of bubbles, and pressure time histories of shock waves in water were investigated numerically.
因为压力脉动减小导致流速增加，从而使冲击噪声和涡流噪声略有增加。
Because velocity of flow reduces when the pressure pulse reduces, the noise of impulsion and the noise of vortex increase a little.
