Critical Speed of a Shaft

Critical Speed or Whirling Speed. The critical speed is the angular velocity that excites the natural frequency of the rotating objects like rotors, shafts…etc., resulting in severe vibration of the shaft in the transverse direction. Critical speed is also known as the whirling speed of the shaft. Let us derive the governing equation of the critical speed.

Critical speed

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. The resulting …

Critical Speed Calculator for Runners

As mentioned above, we can calculate critical speed in different ways for runners. The most accurate and time-consuming way requires multiple maximal efforts above CS (think 3 to 20 minutes in duration) to draw the speed/duration relationship. From this data, we are able to extrapolate the athlete's critical velocity.
