| 中文摘要: |
| 对两层金属平板、中间橡胶夹芯的结构进行了设计,认为金属平板和芯层中都有纵波和横波的传播,应用传递矩阵法建立了平板夹芯结构声学设计的理论模型.利用该模型设计出一种钛板夹芯结构,并对该夹芯结构进行了透声性能分析.数值计算结果表明该方法设计出的钛板夹芯结构具有良好的透声性. |
| 英文摘要: |
| A sandwich structure, in which the intermediate layer is rubber and the others are metal plates, is considered as sound transmission window.It suggests that both the longitudinal wave and transverse wave can transmit in the metal plate and rubber.By using transfer matrix, a plate sandwich model for acoustic designing is established.A titanium sandwich construction is designed by the model, and the sound transmission performance is analyzed for the construction.Numerical analysis shows that the titanium sandwich construction has good sound transmission. |
