| 摘 要： | 减少圆柱壳振动和噪声的一种有效方法是在其表面敷设阻尼层,这种复合结构称为阻尼复合圆柱壳.分别运用薄壳理论和弹性理论描述了阻尼复合圆柱壳的内壳和阻尼层,并在此基础上提出了计算阻尼复合圆柱壳振动功率流的一种新方法.通过数值计算,得到了内外壳体厚度对复合圆柱壳振动功率流的影响规律,为圆柱壳减振降噪措施的应用提供了理论基础. |
| 关 键 词： | 复合圆柱壳 振动功率流 傅立叶变换 弹性理论 减振降噪 |

| Abstract: | An effective way to decrease the vibration and noise of cylindrical shell is to coat the shell with damp layer,known as damped cylindrical shell.The motion equations of the inner shell and coated layer of the damped cylindrical shell are described by the thin shell theory and elastic equations respectively,and a new method for calculating the vibration power flow is proposed.Through changing the thickness of the inner shell and coated layer,the influence of thickness to the vibration power flow is concluded... |
| Keywords: | damped cylindrical shell vibration power flow Fourier transform elastic equation vibration/noise reduction |
