Digital computer simulation of a piezoelectric thickness vibrator
TLDR
In this article, a model for an ultrasonic transducer, which allows direct evaluation of the time response by means of digital computing techniques, is described, where the piezoelectric thickness vibrator is represented by lumped elements, i.e., capacitor, inductor, and current-controlled current source.Abstract:
A model for an ultrasonic transducer is described which allows direct evaluation of the time response by means of digital computing techniques. In analogy to the equivalent circuit of a transmission line, the proposed model represents the piezoelectric thickness vibrator by lumped elements, i.e., capacitor, inductor, and current‐controlled current source. Simulation of the model is easily available by applying standard electrical network analysis techniques. The time behavior of an ultrasonic transducer, transmitting or receiving planar longitudinal sound waves, is calculated.read more

A Three Port Model for Thickness Mode Transducers Using SPICE II
C.G. Hutchens,S.A. Morris +1 more
TL;DR: In this article, a model based on Schwarz's artificial transmission line (ATL) model was developed for use on the SPICE I1 circuit analysis program, which uses lumped elements configured as two stages, the first stage consists of a T type artiticial transmission line which models the acoustic behavior of the transducer.

Novel graph model and analysis method for piezoelectric thickness-drive transducers
TL;DR: The proposed TWSF graph model, expressed via electrical and acoustical variables instead of electromechanical analogy, simplifies understanding of the physical mechanism of the transducer and offers a more efficient technology to obtain precise results with less analysis.
