Piezoelectric energy harvesting from galloping of a prism mounted on a nonlinear support

This abstract has open access
Summary
The piezoelectric energy harvesting from the galloping of a rigid prism is numerically investigated. The prism is mounted on a bimorph piezoelectric cantilevered beam and on a nonlinear spring whereas the aerodynamic force is computed using the classical quasi-steady approach. The results for four configurations are presented in this article: two bistable nonlinear energy harvester, a monostable nonlinear energy harvester and a linear energy harvester. Among other aspects, results show evidences of chaotic responses for bistable configurations.
