Optimization of Damping of Laval Rotor Bearings

Optimal damping in Laval rotor bearings, based on a model of a rotor in isotropic bearings with one-and-half-degree-of-freedom is found. Eigenmotions, in general, are damped vibrations and an exponentially decreasing motion. Only in a limited range of parameters there are not a damped vibrations, but all three eigenmotions are exponential motions with various decreasing rates. The most influence on resonant maximum has the damping. Minimal maximum depends of damping in bearings. The obtained damping is optimal, but it is difficult to realize in praxis.
