One of the most critical issues encountered in structural applications is the presence of undesirable vibrations, which can adversely affect the performance, safety, and reliability of a system. As a result, there is growing demand for lightweight, efficient, and durable structures that minimize the excessive use of resources. Piezoelectric materials offer a promising solution in the field of vibration damping, as they possess the unique ability to convert mechanical energy into electrical energy and vice versa. Furthermore, when coupled with shunt circuits, such as resistor-inductor (RL) circuits, they can form effective vibration suppression mechanisms, capable of adapting to the dynamic requirements of the structure. This thesis investigates the application of shunt circuits in piezoelectric systems for the damping of vibrations in smart structures, with the main challenge being the identification of optimal electrical circuit parameters. The study focuses on a cantilever beam incorporating an engraved additive microstructure, on which a piezoelectric patch is mounted. Through static, modal, and harmonic analysis using ANSYS software, the mechanical and dynamic behavior of the system is evaluated, along with the tuning of resistance and inductance values within the circuit. The objective of this research is to enhance vibration suppression by achieving optimal system parameterization.
