| 摘 要： | 根据无限大弹性体和粘弹性体的波传递理论，对水下和空气中含流夹层的弹性－粘弹性阻尼复合板的隔声性能进行了研究，即具体处理了４阶方阵与２阶方阵之间的转化问题，避免了方程奇异。通过计算得到：水层厚度的增加使结构传声损失增大；软质阻尼材料能明显改善结构的隔声性能。

| Abstract: | The sound insulation properties of layered damping panels with fluid interlayer in water and air based on the wave travelling theory in infinite elastic and viscoelastic panels of infinite extent are discussed. The problem of transition from square matrix of order 4 to square matrix of order 2 is solved to avoid the singularity of equations. The conclusions are drawn by calculation: with the increase of the thickness of water layer,the STL of structure is enhanced significantly; the sound insulation performance of structure is improved obviously by using flexible viscoelastic materials. |
