Abstract

This research is concerned with development of the passive-active vibration absorber using piezoelectric actuators. This active-passive isolation system consists of 4-pairs of PZT actuators bonded on accordion type of mounting bracket and a spring-damper located in center. Hence, the active system is connected in parallel to the passive system. In this paper, we discuss the dynamic characteristics of the addressed system. Based on the series of experiment, it is found that the proposed system can cope with the external disturbances. The controller design is currently under investigation.
