ELECTROAEROELASTIC ANALYSIS AND STABILITY OF GALLOPING-BASED Triangular Harvester

Abstract

With most of the countries using the maximum hydro power they can extract from natural resources, the trend has been shifting towards alternate means. Energy harnessing through vibrating bodies has come out as a very favourable option. Various transduction mechanisms can be used to convert the energy from mechanical vibrations to electrical energy. The ease with which one can get power through environment friendly means and an extremely small setup by volume and cost are the major advantages piezoelectric transduction mechanisms poses. Keeping in mind the changing trends of energy extracting methods, current work focuses on the potential and dynamics of piezoelectric energy harvesting from special class of aero-elastic vibrations called transverse galloping. Different nonlinear dynamics techniques including method of multiple scales and shooting method are used to characterize the harvester’s response and determine the contribution of present nonlinearities in the system’s response.
