CONTRIBUTION IN CALCULATION OF ULTRASONIC TRANSDUCERS USED IN METAL REWORKING PROCESS BY WELDING IN ULTRASONIC FIELD

Abstract

The paper presents the calculation and construction elements for the ultrasonic transducer system used in reworking by welding in ultrasonic field.The transducer is modeled by the finite element method analysis to determine the diagram of particle velocity amplitude variation along the ultrasonic transducer. All items ultrasonic system are made to work under the resonant frequency of 24kHz, respectively, at 25 kHz resulting in the optimal finite element analysis.
