    Feedback Control of Journal Bearing Instability

  • Original language description

    The interaction between the rotating system and the oil film in journal bearing causes an undesirable dynamic behaviour, which is called the oil whirl and the oil whip. The presented paper deals with the reduction of oil whirl effects by means of the feedback control of the bearing shell by kinematic excitation. The numerical simulations were performed for the rotor system supported in journal bearings without feedback control and with PD feedback controller as well. The influence of PD controller parameters of the equilibrium position, the stability in small surrounding of the equilibrium position, the response on the unbalance force excitation and the vibration oil whirl rise limit are determined.
