Vibration Control Using Three-Layer Sandwich Beam

B. P. Yadav

ABSTRACT: This paper discusses vibration analysis of three-layer sandwich beam. The present work deals with the analysis of vibration of the primary system having a mass and rubber spring mounted on a three-layer simply supported symmetrically arranged with elastic faces and viscoelastic core sandwich beam. Based on the derivation of R.C. Das Vikal et. al, for response of harmonically excited mass and for transmissibility, the effectiveness of three-layered sandwich beam of viscoelastic core for central mounting of the primary system is evaluated. The thickness of viscoelasticcore is varied to get minimum value of response and transmissibility.
