In this study, the electromechanical equation of motion for a galloping-based energy harvesting system is derived and experimentally validated. This system consists of a bluff body that elastically mounted in fluid flow and a piezoelectric energy harvesting device, which is placed inside it. To confirm dynamic behavior of the system in fluid flow, periodic response of the variables is analytically obtained by employing the harmonic balance method. The validated equations are used to study effect of changing the system parameters on electromechanical behavior of the energy harvester. Then, application of the system is investigated in a realistic condition. Employing several user-oriented charts, the energy harvesting system is optimized and it is shown that this system can optimally be used in normal wind speed.
