Design and simulation analysis of ultrasonic extrusion transducer

Based on the wave equation and frequency equation, an analytical model of the ultrasonic vibration squeeze transducer is established, and the structural dimensions of each part of the piezoelectric transducer are calculated. The ANSYS finite element software was used to establish a finite element model on the basis of statics analysis for modal and harmonic response analysis. The traditional analytical method was used to design a 20kHz sandwich piezoelectric transducer for axial vibration. The impedance analyzer is used to measure the transducer, and the impedance-frequency characteristic curve of the transducer is obtained. The results show that the test value is basically the same as the simulation value, and the structural parameters meet the requirements, verifying the rationality of the structure.
