ANALYTICAL MODELING AND FEM SIMULATIONS OF ENERGY HARVESTING CANTILEVER BEAM

The concept of energy harvesting systems allows sustainable sources, such as mechanical energy, to be harvested from the environment. feature piezoelectric material generate voltage a result its deformation characterizes them an tool, due their robustness and efficiency characteristics. This paper shows numerical modeling cantilever beam using Euler-Bernoulli method. FEM simulations have been created in order determine optimal position transducer along beam. Furthermore, these conclusions used develop mathematical model MATLAB investigate effect geometry characteristics on output parameters. impact dimensions effective area location well effects studied obtain terms efficiency. Once phase has completed, results regarding generated power system compared models validated.
