Power Harvesting From Vibration Using Magnetostrictive Materials
Paper i proceeding, 2006
The paper addresses the problem of vibration-to-electric energy conversion using magnetostrictive materials. An overview of both theoretical and experimental results of the study of performance of the magnetostrictive electric generator (MEG) which was built at Chalmers University of Technology is presented. An inverse dynamics based algorithm has been proposed for modeling and for optimizing of generator design. The algorithm was implemented in Matlab/Simulink and used for dynamic analysis of the considered controlled magnetoelastic electromechanical system under different periodic excitations of its hosting structure. Both simulation results and experimental data have confirmed functionality of the designed MEG using giant magnetostrictive material Terfenol-D.
