Identifying the speeds at which a rotor's natural frequency is excited, potentially causing catastrophic failure. turbomachinery rotordynamics with case studies pdf

This determines if the rotor-bearing system is prone to self-excited vibrations, often caused by fluid forces in bearings or seals (commonly known as "oil whirl" or "whip").

The following examples highlight how rotordynamic analysis resolves real-world mechanical failures: Turbocharger Bearing Instability:
