Claim 12:
13. A method for damping vibration of a turbomachine, the method comprising:
providing a rotor damping device comprising a first fluid damper and a second damper in communication with the first fluid damper, the second damper comprising a wire mesh, the second damper mounted on a squirrel cage configured to take up an axial load, wherein the first fluid damper transitions between a working condition in which the first fluid damper dampens vibration of the turbomachine and an interruption condition in which the first fluid damper does not dampen vibration of the turbomachine; and
damping vibration of the turbomachine with the second damper during the interruption condition,
wherein the second damper is in parallel configuration with the first fluid damper.
