The numerical analysis of vibro-acoustic characters of a ship was carried out by use of structural FEM and acoustic BEM. 摘要交替運用結構有限元法與聲學(xué)邊界元法，對某型艇振動(dòng)聲學(xué)特性數值計算問(wèn)題進(jìn)行了研究。
As an example for application, the rotating monopole point source is assumed to form the simple harmonic motion in a cylindrical cavity and its acoustic performance is obtained. 進(jìn)而利用該頻域解計算分析了旋轉簡(jiǎn)諧單極子點(diǎn)源的聲學(xué)特性。
