What is meant by critical speed of a shaft which are the factors affecting it?
In solid mechanics, in the field of rotor-dynamics, 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. The factor which affects the critical speed of a shaft is diameter of the disc, span of the shaft, and eccentricity.
How to Calculate Additional Deflection of Centre of Gravity of Rotor using Natural Circular Frequency?
Additional Deflection of Centre of Gravity of Rotor using Natural Circular Frequency calculator uses Additional Deflection of C.G of Rotor = (Angular Velocity^2*Initial Distance of Centre of Gravity of Rotor)/(Natural Circular Frequency^2-Angular Velocity^2) to calculate the Additional Deflection of C.G of Rotor, Additional Deflection of Centre of Gravity of Rotor using Natural Circular Frequency formula is defined as a measure of the rotor's centre of gravity displacement from its initial position when the rotor is subjected to a critical or whirling speed of shaft, which is a crucial parameter in determining the stability of rotating machines. Additional Deflection of C.G of Rotor is denoted by y symbol.
