초록 ▼

A system for controlling vibration of a dynamic surface includes at least one sensor in communication with the dynamic surface for measuring vibration of the dynamic surface and generating a feedback signal proportional to the measured vibration and at least one piezoelectric actuator in communication with the dynamic surface and in communication with the controller for receiving the output signal. The system also includes at least one mass overlying the at least one piezoelectric actuator, whereby the at least one piezoelectric actuator lies between the mass and the dynamic surface, and a controller in communication with the at least one sensor for receiving the feedback signal, generating an output signal in response to the feedback signal and sending the output signal to the at least one piezoelectric actuator. The piezoelectric actuator applies a counter force between the dynamic surface and the mass upon receiving the output signal for reducing or controlling vibration of the dynamic surface.
