Design and Simulation Technology of Piezoelectric Ultrasonic Transducer with Sandwich Composite Horn

Abstract

The structural characteristics of piezoelectric ultrasonic transducer with sandwich composite horn are expounded,the vibration characteristics are theoretically analyzed,the velocity distribution equation and stress distribution equation of transducer under longitudinal vibration are obtained,the frequency equation is given,and the piezoelectric ultrasonic transducer with compound amplitude-changing rod is designed.Then the modal analysis and harmonic response analysis of the transducer are carried out by using the finite element simulation software Workbench,comparison between the results obtained and the theoretical values,the error is very small, which meets the need of engineering practice and verifies the correctness of the derivation design.
