Abstract : A theory is presented for the effect of a tuned damper consisting of a mass connected through a link of viscoelastic material to the center of a clamped-clamped beam. Effective loss factors for the beam-damper system are defined and experiments are described which confirm the main conclusions of the theory. Practical, lightweight damper unit designs are illustrated. These were used in the experimental investigation. (Author)
