| 中文摘要: |
| 对比自由阻尼结构和约束阻尼结构的阻尼性能，研究基板、阻尼层、约束层对约束结构阻尼性能的影响。结果表明：约束结构阻尼性能相较于自由结构更好；约束阻尼结构中，基板越薄，阻尼层和约束层越厚，复合结构阻尼性能越优异。 |
| 英文摘要: |
| The damping properties of free and constrained damping structures were comparatively investigated as well as the effects of substrate，damping layer and constraint layer on the damping properties of constrained structure.The results showed that the damping property of constrained structure was better than that of free structure. In the constrained structure，when the substrate was thinner，and the damping layer and constraint layer were thicker，the damping property was better. |
