Method for calculation of piezoceramic transducer transmission characteristics in the mode of ultrasonic waves radiation. Part 1. Calculating the coefficient of electromechanical conversion
Main Article Content
Abstract
Definition for transmission characteristic of ultrasonic piezoelectric transducer is given in article and calculation of electromechanical transformation coefficient from electric input to the mechanic side of piezoelectric transducer is accomplished. Question of influence of liquid contact layer to frequencydependent variation of electromechanical transformation coefficient is described in first time. In case then area of mechanical contact with acoustic load have a finite size the liquid contact layer is the resonator of radial oscillation and it render a significant influence to frequency characteristic of piezoelectric oscillator.
