Abstract
A pulsed operating mode of a piezoelectric plate placed into a liquid is considered. The problem is solved for the application of exciting electric pulses with a duration that is a multiple of the duration of a sinusoid half-period at the natural frequency of a piezoelectric plate. For different degrees of plate damping, the dynamics of changes in the shape of an acoustic pulse are studied as a function of an electrically excited pulse duration. The durations and amplitudes of acoustic signals are evaluated. The problem is solved by the calculation-theoretical method via application of both the apparatus of schemes-analogues of piezoelectric transducers and the spectral method based on a Fourier transform.
