| 摘 要： | 将蜂窝夹层结构引入到水下噪声控制方面,基于弹性体和粘弹性体的波传递理论,采用传递矩阵的方法,探讨了垂直入射下蜂窝夹层结构在水中的隔声性能,并与其它结构的隔声性能进行比较。研究表明:蜂窝夹层结构的隔声性能整体要比打孔橡胶夹层结构和均质橡胶结构好;蜂窝面层橡胶材料的性质对蜂窝夹层结构隔声性能影响较大,采用软质橡胶可以取得更好的隔声性能。

| Abstract: | The paper applied honeycomb truss structures to underwater noise control. Based on the sound wave transfer theory of elastic and viscoelastic materials, with the transfer matrix method, the paper studied sound insulation properties of underwater honeycomb truss structures under the condition of normal incidence and compared the sound insulation properties with those of other structures. The study shows that sound insulation properties of underwater honeycomb truss structures are better than rubber sandwich structures with apertures and homogeneous rubber structures. The properties of external rubber material have larger effects on sound insulation properties of honeycomb truss structures; soft rubber material has better sound insulation properties than hard rubber material. |
