| Abstract: | Abstract: Regarding the design of viscoelastic damping treatments, constitutive equations of the
viscoelastic material and the design method based on modal calculation are discussed. The modal combination method is demonstrated by numerical calculation and experiments. The results indicate
that it is a feasible method in the design of viscoelastic damping treatments to reduce the surface
vibration and the noise of structures. |
