Abstract

Based on the friction reduction effect of ultrasonic oscillations, ultrasonic oscillations are utilized to vibrate the cylinder outside barrel, and the static friction characteristics of pneumatic cylinder under ultrasonic oscillations have been investigated. The cylinder sample employed is a standard double rod cylinder with a cube body, and the ultrasonic oscillator has a measured resonant frequency of 31.65 kHz. The two components are connected through screw thread for effective oscillations. A measurement system is established and the influence of ultrasonic oscillator´s frequency, exciting voltage and relative exciting position on static friction characteristics is explored. The experiment results prove the existence of cylinder friction reduction with ultrasonic oscillations compared to that of non-oscillation. And the static friction can be reduced to 60% of non-oscillation friction around the oscillator´s resonant frequency.
