Escape from the potential well of bistable vibration energy harvesters using buckling level modifications

Abstract

During the last decade, nonlinear vibration energy harvesters (NVEH) have attracted research interests for their broadband characteristics. However, they also exhibit low-power orbits in which they may remain stuck, leading to poor harvesting performances. In this paper, we study an orbit jump strategy that allows to jump from one of these lowpower intrawell orbits to high-power interwell orbits. This orbit jump strategy is based on the variation of the buckling level of the bistable vibration energy harvester. We start with a brief presentation of the system dynamics, then we analyze the performances gain with the proposed approach.
