VIBRATION INVESTIGATION OF A RIGID ROTOR SUPPORTED BY HYDRODYNAMIC BEARINGS CONTROLLED BY KINEMATIC EXCITATION
Original language description
The hydrodynamic bearings are marked for considerable damping and high loading capacity and therefore, they are often used as coupling elements placed between the rotor and its casing. After exceeding a limit speed of rotation, the hydraulic forces acting in the bearings induce a self-excited vibration of the system of large amplitude. In this paper, a concept for its suppression based on controlled kinematic excitation of the bearings shells is presented. The performed computer simulations prove that the investigated technique enables to reduce amplitude of the rotor vibration produced by their unbalance, to suppress amplitude of its self-excited vibration and to increase the rotor revolutions, at which the self-excited vibration begins.
