Piezoelectric shunt damping techniques for vibration and noise reduction

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Piezoelectric shunt damping is a passive vibration reduction technique by means of a piezoelectric patch and a shunt circuit. When a structure vibrates, its vibration energy is converted into electrical energy so as to dissipate it as heat at a circuit. This technique is very effective for reducing vibrations at resonance frequencies because it requires a simple circuit along with a piezoelectric patch. This chapter explains its fundamental principle in terms of resistive shunt, resonant shunt and multi-mode shunts made by blocking circuit or negative capacitance circuit. Modeling, shunt parameter tuning and implementation of the shunt circuits are explained. For applications, vibration and noise reduction for smart panels are introduced. Since this technology has merits in terms of compactness, low cost, robustness and easy to install, practical applications in many vibration and noise problems are anticipated.
