Numerical study of parameters influence over the dynamics of a piezo-magneto-elastic energy harvesting device

Resumo

This work deals with the study of a piezoelectric energy harvesting device, aiming to identify parameters value that produce chaotic and non-chaotic behavior. Two different initial conditions sets are analysed. For each one, bifurcation diagrams where forcing amplitude and excitation frequency are varied, are computed and analysed, showing the existence of chaotic and regular regions.
