Active Air Bearing using Squeeze Film

Takaaki OIWA, Shigeru MATSUDA and Takashi MATSUDA


This paper proposes an active air bearing based on squeeze film using ultrasonic magnetostrictive actuator. The squeeze film generated by the oscillating actuators lifts and positions actively the floating object. Experimental results showed that the ultrasonic oscillation eliminated residual vibration of the object, and the magnetostrictive actuator lifted and positioned the object simultaneously.
