    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.
