| 英文摘要: |
| Based on Mindlin's plate theory,a dynamic equation of a visoelastic circular plate waveguide is presented in this paper.By investigation the propagation and energy disspation principle on the basis of constitutive relation of viscoelastic materials,it shows that a viscoelastic circular plate waveguide absorber has a good effect on vibration dampling and stimulation.And the results validate that the energy disspation ratio is rela ted with parameters of geometry,material and travelling wave frequency. |
