Abstract
This paper summarizes the design, fabrication and experimental
evaluation of an adjustable squeeze-film damper to control radial vibration on
a rotating shaft. Conventional squeeze-film dampers are widely used on high
speed rotors to provide radial damping. For this semi-active design,
controllability is realized by replacing the conventional damping fluid with
a magneto-rheological (MR) fluid. The shear strength of the MR fluid can be
adjusted in realtime by manipulating voltage to electromagnets which surround
the bearing. Experimental evaluations are conducted on a highspeed (0-10000
rpm) test rig. The results show that the damper has a significant effect on
the rotor responses near resonance regions
