Piezoelectric structural vibration control

Abstract

Over the last two decades, piezoelectric materials have been extensively used as components in active and passive structural vibration control solutions. The most frequent applications consider piezoceramic thin patches bonded to thin structures subjected to bending. For active vibration control solutions, the piezoceramic patches can be used as strain sensors and/or bending actuators when connected to properly designed signal conditioning, processing, and amplification. For passive vibration control solutions, they can be used as vibration dampers and/or absorbers when connected to properly designed electronic shunt circuits. The objective of this chapter is to present some examples of the use of piezoelectric materials, as distributed sensors and actuators, for the development and implementation of passive and active vibration control solutions.
