- •
A bistable 2-DOF energy harvester with magnetic coupling is proposed, hybridizing multimodal method and nonlinear dynamics.
- •
The linear parasitic oscillator attached aims for two resonant peaks and the magnetic coupling engages nonlinear dynamics.
- •
The evolvement of nonlinear responses with the adjustment of the parasitic oscillator is shown.
- •
One strong nonlinear peak in addition to a quasi-linear peak is achieved by adequately adjusting the parasitic oscillator.
- •
The load resistance has significant influence around the peak with strong nonlinear responses in terms of peak shift.
