Vibration Suppression and Energy Harvesting of for an Elastically Supported Beams with NES-GMM
This paper investigates the vibration suppression and energy harvesting problems of elastically supported beams with Nonlinear Energy Sink and Giant Magnetostrictive Materials(NES-GMM).Based on Hamilton's principle,Galerkin method,the governing equations of the coupled beam,NES-GMM system are derived.The response of the beam under harmonic excitation is numerically solved by the fourth-order Runge-Kutta method.The vibration suppression effect of NES-GMM on the beam was ana-lyzed in both time and frequency domains.A detailed numerical study is carried out to investigate the effects of the structural parameters on the vibration suppression and energy harvesting of the NES-GMM.The results indicate that the NES-GMM system is highly effective in suppressing multimodal transverse vibrations of elastically supported beams under harmonic excitation,showcasing a notable de-gree of independence in its vibration suppression and energy harvesting capabilities.
