PREDICTION METHOD OF FLOOR VIBRATION REDUCTION BY CONTROL SYSTEM USING FILM TYPE PIEZO-ELECTRIC DEVICE

Abstract

This paper proposes a prediction method of floor vibration reduction by control system using film type piezo-electric device. The prediction method is based on the FEM. Detailed FEM models of piezo-electric device and floor structure can express the quite minute behavior of them, and vibration reduction can be calculated by the results of the FEM. Moreover, the validity of the prediction method was confirmed by an observation result of trial designing of a scaled floor.
