| Purpose The present work examines the influence of additional moderate amplitude high-frequency (HF) excitation on energy harvesting (EH) in the inertially excited bistable Duffing-type harvester with nonlinear damping. Method By introducing the slow and fast time scale we split the dynamics of the electromechanical system and obtain the effective hardening mono-stable potential. Results The higher power output was found analytically in the main resonance area of the slow dynamics effective system. In addition, numerical simulation is conducted to support the analytical predictions. Conclusions The excited high-frequency components change the properties of the dynamic solution, transforming it from a double-well to a single-well in the original system, providing an opportunity to study the phenomenon of vibrational reso- nance as a useful energy mechanism. |
