Critical speed - Wikipedia

In solid mechanics, in the field of rotordynamics, the critical speed is the theoretical angular velocity that excites the natural frequency of a rotating object, such as a shaft, propeller, leadscrew, or gear.As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration.
