Non-Linear Dynamics and Optimization of a Harvester–Absorber System

In this paper, we propose a novel concept of a harvester-absorber system. The idea is based on usage of the dynamic absorber for energy harvesting. The device consists of three elements: a main system (damped body), a pendulum (tuned mass absorber) and an electromagnetic harvester. The ultimate goal of this investigation is to achieve simultaneous mitigation of vibrations and energy harvesting. We show the dynamics of the system and ranges of parameters where we observe good damping properties and high energy recovery. Additionally, an optimization of the harvester device parameters has been performed.
