In the following thesis, we will analyze and study the techniques of the multi-mode resonant shunts as a method of damping, for the suppression of oscillations in a complex construction of smart beams. This method is based on electronic elements (resistors, inductors, and capacitors) that work as an impedance. Specifically, the energy that is produced from the oscillations of the device, is converted into electric energy through the piezoelectric elements is transferred to the electronic circuit, where it is consumed and as a result, vibration damping is achieved. In the present thesis, the construction of the beam with upper and lower piezoelectric patches will be modelled with the program COMSOL Multiphysics and will be simulated using modal analysis tools. For the study of the multi-mode resonant shunt, “Current-flow” and “Current-Block” circuits will be used. The objective is the comparison of the two different types of circuits but also the analysis of the results to confirm the aforementioned theory.
