Sažetak
In this paper Crandalls bearing force-velocity model is applied to stability analysis of radial loaded Laval rotor in cylindrical fluid film bearings.
A domain of rotor speed and transverse bearing loads, which provides stable support and introduces heavy damping of rotor vibration, is obtained by standard computational routines. As a result of this analysis, the stability boundary is determinated for different values of rotor damping parameters. The stability regions based on Crandalls force-velocity model agree with practical observations of rotor dynamic behavior and with the experimental data.
