Good choice of hybrid piezoelectric damping configuration based on control power requirement-series type versus separated type

摘要

This paper aims at presenting the advantage of the separate type of the hybrid piezoelectric damping comparing with the previous hybrid piezoelectric damping from the viewpoint of active control power requirement under the severe vibration suppression performance condition, numerically and experimentally. The separate type of the hybrid piezoelectric damping has been proposed by the authors, in which active voltage source and passive tuned RL shunting circuit are separated from each other, and piezoelectric actuators to be used to active and passive dampings are placed different location on the host structure. Simple flexible cantilever beam with surface bonded piezoelectric ceramic tiles is used as a test structure.
