Original Kurzfassung:
For a gyroscopic rotor in active magnetic bearings,
the rigid body natural frequencies and mode shapes are
investigated. An impulsive excitation force is generated by two
rectangular pulses in the current control reference signal. With
vibration measurements available in two perpendicular
directions for each bearing, experimental modal analyses are
performed at rotational speeds up to 100000 rpm. Identification
results demonstrate the gyroscopic split of natural frequencies.
