- Abstract
- Converting vibrating energy of Magnetostrictive materials into electrical energy can be used in the manufacture of micro-generators, MEMS systems and sensors. Magnetostrictive materials behavior is nonlinear, but under the right conditions it can be assumed as linear behavior. In this paper, linear modeling of vibration energy using a single degree of freedom mass - spring – damper in natural frequency 250 Hz has been studied. The equivalent mass of the system is considered as a substrate on which a layer of Metglas2605SC metal is attached. In the present work, the effect of the random force is applied to the system support, as well as a comparison between the amounts of harvested energy while the support of the harmonic excitation has been studied. Finally, numerical results are presented for five different substrates.
