A New Approach to Piezoelectric Shunt Damping
نویسنده
چکیده
Piezoelectric transducer (PZT) patches can be attached to structures in order to reduce vibration. The PZT patches essentially convert vibrational mechanical energy to electrical energy. The electrical energy can be dissipated via an electrical impedance. This paper introduces a method of implementing an arbitrary impedance using a current source and digital signal processor (DSP). The \synthetic impedance" is used to implement a piezoelectric shunt damping circuit for a resonant simply-supported beam.
