Basic Study on Reduction of Rotational Vibration Using Linear Oscillatory Actuator

Abstract

　Rotational vibration causes an increase in vibration and noise and is a problem in various transportation equipment including automobiles. This paper proposes a new method of rotational vibration suppression using a linear oscillatory actuator driven in the radial direction. Numerical calculations show that the Coriolis force increases as the mover oscillates in the radial direction due to the electromagnetic force generated by the LOA.
