Abstract

This paper aims at proposing an integrated design method of the active/passive hybrid type of the piezoelectric damping system for reducing the dynamic response of the flexible structures due to external dynamic loads. The design method is based on the numerical optimization technique whose objective function is the active control power requirement of the damping system. The vibration suppression performance, which is evaluated by the maximum value of the gain of the frequency response function of the structure, is constrained. In order to demonstrate the effectiveness of the proposed integrated design method, numerical simulation and laboratory experiment will be done using a three-story structure model equipped with 12 surface bonded PZT tiles pairs. The results indicate that the optimally designed hybrid piezoelectric damping system successfully achieves excellent performance comparing with the pure active piezoelectric damping system from the viewpoint of the control power requirement.
