Abstract

Highlights: The novel model of the system for vibration mitigation and energy recovery is proposed. The harvester device added to dynamic vibration absorber does not reduce the efficiency of vibration mitigation. The activation of a tuned mass damper can improve energy harvesting at low frequencies. Abstract: The paper presents a novel system for simultaneous energy harvesting and vibration mitigation. The system consists of two main parts: an autoparametric pendulum vibration absorber and an energy harvester device. The recovered energy is from oscillation of a levitating magnet in a coil. The energy harvesting system is mounted in a pendulum structure. The system allows energy recovery from a semi-trivial solution (pendulum in rest) or/and swinging of a pendulum. The influence of harvester parameters on the system response and energy harvesting in a parametric resonance is studied in detail. The harvester device does not decrease vibration reduction effectiveness.
