Vibration Control Using Piezoelectric Connected with Shunts Circuits

Abstract

The study analyzes the dynamic behaviour and vibration attenuation of an Euler Bernoulli beam coupled with a piezoelectric layer. The vibration attenuation is given by the shunt circuit connected to the piezoelectric. This paper shows different shunt circuit impedances and how they affect the system's frequency response (FRF) functions. The spectral element method is used to model the intelligent material under analysis and has its function based on the exact solution of the wave equation, therefore, a single element is necessary to model the structure. The estimated responses for each shunt configuration express a relationship with the passive components used in the respective circuits. In each case, the circuit has a particular effect on FRFs.
