Vibration Control of Rotating Shaft with Self-optimizing Support System

Abstract

This paper proposes a new design concept of a self-optimizing support system for a rotating shaft. The purpose of this support system is to provide the self-tuning for the support stiffness such that the vibration of a rotating shaft usually occurs at the near antiresonance with changes of a rotating speed. The optimal tuning values of support stiffness are obtained by the on-line estimations of rotating angular velocities of a rotating shaft. The effect of the self-optimizing support system is proved by the tests of nonstationary responses for a fundamental rotor-shaft system.
