| Abstract: |
| 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. |
