Vibroimpact Motion of Rotor taking into account Friction at the Contact

Vibroimpact motion of system “high-speed, flexible, unbalanced rotor rotating inside floating sealing ring” is analyzed. This rotor system was simulated via Runge-Kutta method. Four vibroimpact regimes were discovered. Spectral analysis of these rotor oscillations is made. Increase of rotor vibration amplitude is calculated. Change of rotor revolutions per minute due to contact is appreciated.
