Design of broadband nonlinear vibration energy harvester with magnetic coupling

Résumé

The work reported here deals with the design and modeling of vibration energy harvesting from a nonlinear quasiperiodic structure. This proposed harvesting system consists of moving magnets held by elastic structures and coupled by a nonlinear magnetic force. The harvester has been modeled by forced Duffing equations for each moving magnet, including the geometric and magnetic nonlinearities and the mechanical damping. The forced Duffing equations have been solved using the harmonic balance method coupled with the asymptotic numerical method. The numerical and experimental results of the mistuning effect have been analyzed and discussed in depth.
