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
