Abstract
In this paper, an active dynamic absorber using piezoelectric actuator is proposed. The absorber is made up of a cantilever beam with a weight attached on the free end. The piezoelectric actuator is bonded near the fixed end and a strain gauge also attached near the fixed end is used for feed-back. The principle of vibration control is shown, and experiments using a cantilever beam as the main vibration system are carried out. The effect of vibration reduction has been obviously observed.
