| 摘 要： | 本文通过试验方法研究了高水流冲刷区优化的阻尼降噪结构。该结构为一种新颖双重约束阻尼结构,结构的约束层采用环氧树脂玻璃钢。通过平板试件和船底板模型试验研究,结果证实该结构不仅具有较高阻尼效果,而且适用于高水流冲刷区的恶劣环境,成为该区理想的阻尼结构形式。

| Abstract: | An optimum damping structure for noise reduction applied in the scoured region of high-speed flow is studied by experimental method. This is new double restrained damping structure where glass reinforced plastic is used in the restrained layers. It is confirmed by several model tests that this damping structure not only has a good damping effect, but also can be used in the high-speed flow. It is an ideal damping structure in this region. |
