Critical Speed of a Rotating Shaft - Dunkerley's method
Description
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.
Dunkerley’s method is used in mechanical engineering to determine the critical speed of a shaft-rotor system.
