Effect of Structural Parameters of a Transducer on the Duration of an Acoustic Pulse Transmitted into a Solid

摘要

A damped piezoelectric plate loaded with a solid medium (steel) through a contact layer/wear face/contact layer system is considered. The piezoelectric plate is excited by an electric pulse in the form of a sine half-period at the frequency of thickness vibrations. The duration and amplitude of pulses of the vibrational velocity as functions of the parameters (specific acoustic impedances and wave thicknesses) of transition layers are studied by calculations.
