High-pressure centrifugal compressors often experience subsynchronous instability caused by the gas flowing through seals and impellers .
: Hosted by Texas A&M’s OAKTrust, this report includes detailed analysis of a steam turbine’s vibration issues. It describes "tuning" a rotor model to match actual vibration data and solving the problem by shimming bearing pads to increase system stiffness. Core Reference Materials Turbomachinery Rotordynamics
