摘要：
It is shown that the introduction of torsional ultrasonic oscillations in the deformation source reduces the work of the frictional forces in comparison with the application of radial and longitudinal ultrasound or the absence of ultrasound. The application of torsional ultrasound to the deforming element reduces the contact-friction coefficient by a factor of 20-60, as against a factor of two or less when radial and longitudinal ultrasound is applied to the contact zone. With increase in the rolling rate and decrease in oscillation amplitude of the deforming element, the effectiveness of ultrasound application declines. © Allerton Press, Inc. 2008.
