Mathematical Approach Towards Modelling, Simulation & Experimentation of a Cantilever Structured Magnetostrictive Generator

Harvesting electrical energy from ambient vibration is one of the most interesting topic for present researchers. This technology can be utilized effectively in various field. The paper deals with such technology in theoretical implementation which is based on a power generator using Fe-Ga alloy with large inverse magnetostrictive effect, good machinability and high ductility. In this paper, a very user friendly system of such prototype sensor has been modelled. Such model is very effective for analysing & visualising the coupling characteristics of any magnetostrictive energy harvester having parallel beam structure. Various parameters have been analysed. Also experimental result shows that such kind of harvester can generate electrical energy much efficiently. It is seen that the most efficient prototypes can able to generate several tens of voltage. The input force is assumed to be continuous to get a continuous output characteristic. The continuous output voltage can be rectified & stored in a secondary cell for further use of electrical energy. The modelling is very effective in the field of energy harvesting, vibrational control & materials science.
