On energy harvesting from ambient vibrations through an oscillating pendulum system fixed to a suspended plataform

Abstract

In this paper, we present numerical investigations of a pendulum system to harvest energy from the ambient. The mathematical model of the pendulum is obtained considering a harmonic displacement of its base. For power generation, two pneumatic pistons are introduced to generate compressed air. Numerical simulations demonstrate that the largest amount of energy harvesting happens in these chaotic regimes.
