Description/Abstract
Power harvesting systems generate electric power
from mechanical vibration using electromechanical
transducers. To assess the practical performance of
these systems, it is important to be able to estimate
the maximum power that could be harvested from a
specific structure and to derive the optimal conditions
for such harvesting. Dampers have been used to
represent idealised power harvester devices, assuming
that a fixed proportion of the power dissipated in the
absorber could be scavenged. Such idealised power
absorbers have been applied to a vibrating plate in
two different configurations: a configuration that
scavenges power from the transverse displacement
and one that gather power from the extensional
displacement at the plate surface. The maximum
power obtainable from such structure has been
calculated for tonal excitation of the structure. The
attenuation of the kinetic energy, due to the application
of the absorber to the structure, has also been studied
in order to find analogies between power harvesting
and shunt damping.
