The special requirements of rotordynamics engineering are illustrated by means of different examples of turbomachines. The differences between the properties of magnetic bearings and the more common fluid film bearings are pointed out in the examples of two turbocompressors. The importance of the bearing support properties are shown for a turbine generator train. The impact of seal forces are demonstrated for the turbocompressor supported on fluid film bearings. Two of the considered seals are honeycomb seals with frequency dependent characteristics. The consequences of the coupling of lateral and torsional vibrations in gears are illustrated for a gear compressor with three pinions. All examples have a practical background from troubleshooting and engineering work although they do not exactly correspond to real cases.
