摘要
A method and the results of a calculation of the temperature of piezoelectric transducers under harmonic excitation are described. The energy dissipation in them depends on the dielectric, magnetic, and coupled electromechanical (piezoelectric) losses, which are determined experimentally. The frequency band in which a minimum of the heating temperature occurs for identical oscillation amplitudes is determined by numerical calculations.
