ACTIVE VIBRATION CONTROL IN ROTATING SHAFTS

Abstract

In this paper, we examine the spatial behaviour of rotating shafts in the neighbourhood of the resonance frequency. In particular, we study the effect of active magnetic damping on the maximum amplitude of shaft vibrations. We formulate a mathematical model describing the motion of the center of a typical cross section of the shaft with and without damping, which can be used to optimize the damping strategy. We compare the measured result and the result of finite element method and the numeric simulation.
