Abstract
This paper aims at presenting the advantage of the separate type of the hybrid piezoelectric damping comparing with the previous series type of the hybrid piezoelectric damping from the viewpoint of active control power requirement. There are three types of the hybrid piezoelectric damping; one is a series type (integrated type, type I) and others are separated types in collocated and non-colocated conditions (types II and III). Simple flexible cantilever beam with surface bonded piezo-elements is used as a test structure. The results indicate that the hybrid piezoelectric damping whose configuration is type II and III are superior to the type I in active control power requirement under the severe vibration suppression performance condition.
