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.
