Description
Summary:The vibrations of the mechanical system in resonance areas manifest both, the risk amplitudes of device response and the relatively high efficiency of energy harvesting. In laboratory conditions to keep the relatively high energy harvesting productivity, the assumed parameters of the shakers have to be secured. Unfortunately, the technical parameters of excitation source devices are restricted by their electrical and mechanical limitations. Hence in this work, the influence of the excitation in the rigid beam direction is analyzed for the composite beam response in the perpendicular flexible direction. We modeled the beams with determined sets of composite layers, and simulated the appeared effect of perpendicular vibrations to the excitation direction. Dissimilar dynamical behavior is observed while the configurations of the layers differ. We focused on the mechanical coupling of the sets of composite beam layers to get an optimal configuration. The energy harvesting is realized by the piezo element attached to the surface of the composite beam.
