| We examine energy harvesting in an aluminum beam with a piezoceramic patch subjected to kinematic harmonic excitation and impacts. Due to a mechanical stopper applied and consequently hardening in the spring characteristic of the beam resonator we observed a broader frequency range for the fairly large power output. Due to nonlinearities, the system appeared to be sensitive to initial conditions showing multiple solutions. The occurrence of resonant solution associated with impacts increased efficiency of the energy harvesting process. |
