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 Natural Circular Frequency of Shaft?
Natural Circular Frequency of Shaft calculator uses Natural Circular Frequency = sqrt(Stiffness of Shaft/Mass of Rotor) to calculate the Natural Circular Frequency, Natural Circular Frequency of Shaft formula is defined as a measure of the shaft's tendency to vibrate at a specific frequency when subjected to external forces, critical to determining the whirling speed of a shaft in rotating machinery, ensuring stable operation and preventing damage. Natural Circular Frequency is denoted by ωn symbol.
How to calculate Natural Circular Frequency of Shaft using this online calculator? To use this online calculator for Natural Circular Frequency of Shaft, enter Stiffness of Shaft (Ss) & Mass of Rotor (m) and hit the calculate button. Here is how the Natural Circular Frequency of Shaft calculation can be explained with given input values -> 67.8233 = sqrt(2.3/0.0005).
