摘要：
A one-dimensional electromechanical model of a piezoelectric transducer, which reproduces excitation of ultrasonic pulses in a product, reception of echo signals, and calculation of waves in all its elements (damper, protector, piezoelectric element, contact-liquid layer, etc.), is considered. The results of calculations of electric and wave processes in a normal ultrasonic transducer, when it operates jointly with a generator of probing pulses, are presented. Good agreement between the calculation and experimental results is demonstrated.
