    Vibration Engineering. When the natural frequency of a rotating (i.e., dynamic) structure, such as a bearing or a rotor assembly in a fan, is energized, the rotating machine element resonates. This phenomenon is called dynamic resonance and the rotor speed at which it occurs is the critical speed.

    critical frequency of machine Structural resonances This is far more common than a critical speed problem. It becomes a problem when some forcing frequency comes close (+/10%) to the resonant (natural) frequency of a structure. The structure can be the machine housing itself or some nearby structure such as a hand rail or I-beam.
