The numerical modeling results of the full-scale experiment with low-frequency pulse excitation of the stack-type piezoelectric generator (PEG) for the energy storage device are described. PEG is a multilayer axisymmetric piezoceramic package. The dependence of the output voltage on the active load rate under the harmonic and non-stationary mechanical action of the PEG is studied. A finite element device model is developed in ANSYS , and a simplified one-dimensional analytical model is analyzed. The experimental results-to-numerical calculation correlation has shown their good convergence which allows using the analyzed numerical models to optimize the PEG design at the given external action frequency and active resistance value of the external electric circuit. In addition, it is found that the frequency dependence of the output voltage of the axial-type PEG is of a complex nature depending both on the compressive pulse loading level and the piezoelectric modulus value of the PEG sensitive element, and on the electrical load resistance.
