Therefore, it is very significant to analyze noise and vibration problem of ship structures in the ship design stage.

因此，在船舶设计阶段就进行船舶结构的振动噪声分析是非常有意义的。

Propeller cavitation degrades propeller performance, erodes blade surfaces, produces noise, and causes vibration on the ship hull.

螺旋桨空泡会降低螺旋桨性能，产生空化剥蚀和噪声，从而导致船体振动。
