Turbomachinery Rotordynamics With Case Studies Pdf __exclusive__

Vibration spectra revealed a massive sub-synchronous peak at approximately 42% of the running speed. This matched the first forward-whirl critical speed of the rotor. The high-density gas passing through the balance piston labyrinth seal was creating an intense aerodynamic cross-coupled stiffness, overpowering the damping of the journal bearings.
