| 内容記述 | Aeroelastic flutter is characterized as an unstable self-excitation of the aeroelastic structure caused due to an undesirable coupling of structural elasticity and aerodynamics. Flutter is very difficult to predict and it can lead to catastrophic structural failure. Various nonlinear phenomena affecting flutter include nonlinearities in structural stiffness and damping, and free-play in joints. Recent work performed under NAVAIR funded project provides deeper insights into how free-play affects flutter behavior. This paper extends the work performed by this project to gain further understanding of flutter dynamics from energy viewpoint and to unravel the energy exchange phenomena occurring between fluid and structure domain. While most of the work in the literature has focused on how to avoid potentially catastrophic onset of flutter, the focus of this paper is to investigate how to harness the energy in otherwise undesirable flutter phenomena. The flutter phenomena of interest is the limit cycle oscillations (LCO) which represent marginally stable structural response. The work in showed a direct correlation of free-play with LCO. This paper presents a concept for energy harvesting system that uses free-play induced LCO as the energy resource and magnetostrictive device that can harness that energy. The concept is presented using a 2-D aeroelastic system. A complete analytical modeling and simulation results are given and energy transfer phenomena are explained. The harvesting mechanism concept is proposed using advanced magnetostrictive materials like Galfenol. | |||||||||||
