Critical speed, английский
- The angular speed of rotating machinery at which excessive vibration is produced; at this speed the periodic disturbing force coincides with a mechanical resonance of the shaft and/or of the machinery or its supports. critical temperature 1. the temperature at which a steel structure cannot carry the service load for which it was designed because of softening of the steel that occurs when it is heated significantly. 2.
- The speed at which a rotating drill stem begins to vibrate excessively; hence by either de¬creasing or increasing the rotational speed of the drill stem the vibration may be reduced or alleviated.
- Speed at which some, usually untoward, phenomenon manifests itself, as for example the rotational speed at which a driveshaft whips or whirls.
