Viscoelastic Damping Layer Design Using Modal Combination and Its Experimental Study

Zhiyi Zhang

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 numerically and experimentally.The results indicate that this method is feasible in the design of viscoelastic damping treatments to reduce the surface vibration and the noise of structures.
