English: Analytically calculated Campbell Diagram of a sample Steam Turbine.

Analysis show that there are well-damped critical speed at lower speed. Another critical speed, at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to safely ignore it.

3D plot of the model is also shown.
