Research Abstract

A lot of vibration suppression methods using piezoelectric elements have been proposed thus far. Usually piezoelectric elements are bonded to beams or plates and coupled to electrical impedance. The performance of such methods is not so high and they are inferior to mechanical vibration suppression methods. In order to improve the efficiency of piezoelectric elements, a new attachment method based on mechanical impedance matching was proposed in this research. The impedance was matched by using spacers. More effective methods using extended spacers in longitudinal direction and negative stiffness were also proposed. The capacitance tunable circuit was also investigated.
