Abstract

The problems existing in the traditional absorber can be solved better by adopting clearance control magnetic dynamic absorber to control the imbalance vibration of rotors. For the special structure of conical electromagnet, stiffness and damping formulas of the electromagnetic dynamic absorber are derived when the current source is taken as the power of the electromagnet, and the law of influence of various parameters on the stiffness and damping characteristics is obtained through numerical analysis. These researches lay theory foundation for further studies on the clearance control magnetic dynamic absorber.
