Webbwhich the planar motion rotor is usually a favorable model for analytical study of the rotor whirl. Rotor whirl has been the subject of the continuing development of rotors. A mechanical model with two degrees of freedom of motion was first used by W. A. Rankine in 1869 to explain the critical speed behavior of rotor-bearing systems. Webb25 apr. 2008 · A test bench for rotors supported by air bearings floating on O-rings is designed in order to study the whirl phenomenon and characterize the stability threshold with damping elements mounted on bearings. The work includes a description of the test bench and some preliminary experimental results. A rotor of 1kg mass and 37mm …
