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, The Additional deflection of centre of gravity of rotor using natural circular frequency formula is defined as the movement of a beam or node from its original position due to the forces and loads being applied. Additional Deflection of C.G of Rotor is denoted by y symbol.
