Abstract: In this study the calculation of 1/2-wave transducer of longitudinal ultrasonic oscillations and one wave transducer of longitudinal-torsion ultrasonic oscillations were carried out by finite element method with use of Abaqus. Dimensions of the concentrator of longitudinal-torsional oscillations and frequency-amplitude characteristics of the transducers of longitudinal and longitudinal-torsional oscillations were defined by calculation. Application of ultrasonic longitudinal-torsional oscillations at tool during surface-strengthening treatment of details made of titanium will allow to reduce adhesion portion of friction in the contact zone. A comparison of results of finite-element calculation of frequency-amplitude characteristics with experimental ones were made and calculation error does not exceed 2.5 %.

Keywords: longitudinal-torsional ultrasonic vibrations, piezoelectric transducer, ultrasonic waveguide, hub of ultrasonic vibration, frequency-amplitude characteristics.
