Abstract

This article presents an analytical model of a harvested power from a Magnetostrictive Euler-Bernoulli cantilevered beam. Most of the cantilevered beam harvesters used a base excitation system to harvest energy. In contrast, this analytical model predicts the displacement and generated power in a cantilevered beam harvester with a fixed base. Furthermore, the effects of internal and external damping are considered. The magnetostrictive material in this harvester is permendur. In comparison to piezoelectric materials and Terfenol-D, permendur has less vulnerability to shock forces and is machinable. This paper reports a mechanical modeling of Euler-Bernoulli beam and a magneto-mechanical model of permendur to find the generated voltage and power of the harvester. Moreover, the analytical model has been experimentally validated. Experiment result shows the generated voltage is 1400 μV and power density is 2.72 W/m3
