Rotordynamics is distinct from structural dynamics because the rotation introduces gyroscopic effects and specific destabilizing forces. A rotor that is statically balanced may fail catastrophically when crossing a critical speed due to uncontrolled vibration. Therefore, understanding rotordynamics is essential for predicting machine life, ensuring safety, and minimizing downtime.
