Abstract : A theory is presented for the effect of a tuned damper on a cantilever beam. The tuned damper consists of a mass connected through a link of viscoelastic material, with high loss factor, to a cantilever 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 which were used in the experimental investigation are also illustrated. (Author)
