A simulation of a piezoelectric generator (PEG) of energy is given. A feature of this generator is the presence of two types of piezo elements: plate-type elements experiencing bending deformations and cylindrical-type elements experiencing compression deformations. The simulation in the finite element complex is presented. The results of the analysis of unsteady oscillations during vibrational pulsed excitation of the PEG base are presented. Variations in the time range of PEG loading are considered. The analysis of output power and operation of individual elements of the generator is given.
