A study of vibrations of a plate with dynamic dampers

Publikováno v: Strength of Materials. 30:616-621

The paper deals with a problem of transverse vibrations of a plate with nonlinear multiple dynamic dampers under harmonic excitations. We derive a transfer function for the plate with the dampers. We report the results of numerical calculations and e
