Development of the Vibration Isolation System using Piezoceramic Sensors and Actuators

압전세라믹 감지기와 작동기를 이용한 방진 시스템 개발

This paper is concerned with the development of the vibration isolation system using piezoelectric actuators and sensors. The active vibration absorber system consists of 4 pairs of PZT actuators bonded on aluminum plates. Hence, the active system is directly connected to the passive system. The rubber attached to the end of the beam is connected to the upper base as a structural member. It allows bending thus maximizing the vertical movement generated by the piezoceramic actuators. The piezoceramic sensors consists of 4 PZT sensors known to tilting, rolling and vertical movement. This paper also presents the development and the movement of the system.
