“…The proposed pseudo-maglev harvester is a crucial component of the laboratory harvester-absorber system, which allows to simultaneously vibration mitigation and energy recovery (Kecik, 2015;Kecik and Mitura, 2016;Kecik et al, 2017a). The detailed study of the maglev harvester helps to proper tune and find the best configuration of the system.…”

The paper presents study of a pseudo-magnetic levitation system (pseudo-maglev) dedicated for energy harvesting. The idea rely on motion of a pseudo-levitating magnet in a coil’s terminal. The study based on real prototype harvester system, which in the pendulum dynamic vibration absorber is applied. For some parameters, the stability loss caused by the period doubling bifurcation is detected. The coexistence of two stable solutions, one of which is much better for energy harvesting is observed. The influence of the pseudo-maglev parameters on the recovered current and stability of the periodic solutions is presented in detail. The obtained results show, that the best energy recovery occurs for the high pseudo-maglev stiffness and close to the coil resistance. The amplitude’s excitation, the load resistances and the coupling coefficient strongly influence on the system’s response.
