Analysis of voltage source control characteristics of clearance control magnetic dynamic absorber

Some 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 equations of the electromagnetic dynamic absorber are derived when voltage source is taken as the power of the electromagnet, and the influence law of various parameters on the stiffness and damping characteristic of the clearance control magnetic dynamic absorber is obtained through numerical analysis. These researches lay theory foundation for further studies on the clearance control magnetic dynamic absorber.
