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 Centrifugal Force Causing Shaft Deflection?
Centrifugal Force Causing Shaft Deflection calculator uses Centrifugal Force = Maximum Mass of Rotor*Angular Velocity^2*(Initial Distance of Centre of Gravity of Rotor+Additional Deflection of C.G of Rotor) to calculate the Centrifugal Force, The Centrifugal Force Causing Shaft Deflection formula is defined as a force that arises from the body's inertia and appears to act on a body that is moving in a circular path that is directed away from the center around which the body is moving. Centrifugal Force is denoted by Fc symbol.
How to calculate Centrifugal Force Causing Shaft Deflection using this online calculator? To use this online calculator for Centrifugal Force Causing Shaft Deflection, enter Maximum Mass of Rotor (mmax), Angular Velocity (ω), Initial Distance of Centre of Gravity of Rotor (e) & Additional Deflection of C.G of Rotor (y) and hit the calculate button. Here is how the Centrifugal Force Causing Shaft Deflection calculation can be explained with given input values -> 0.001756 = 100*11.2^2*(0.002+0.0008).
