Rigid Jeffcott Rotor Bifurcation Behaviour Using Different Models of Hydrodynamic Bearings
Original language description
The paper studies dynamical behaviour of Jeffcott rotor supported by a hydrodynamic bearings. It uses different analytical formulations for hydrodynamic bearing forces acting on Jeffcott rotor. The model is nonlinear due to the presence of hydrodynamic bearings and can show different subharmonic behaviour like oil whip and oil whirl. Such a system is subjected to dynamical analysis using numerical continuation aimed at detection of nonlinear phenomena like bifurcations and unstable behaviours with respect to basic system parameters.
