No shaft can ever be perfectly straight or perfectly balanced. When an element of mass is offset from the axis of rotation, centrifugal force will tend to pull the mass outward. The elastic properties of the shaft will act to restore the “straightness”.

As shown in fig (b), the two forces acting on the rotor when it is rotating, are: Centrifugal force acting radially outwards through CG = m ω² (y+e) Force resisting the deflection (or restoring force) = s y For equilibrium, Centrifugal force = Restoring force ∴ m ω² (y+e) = s. y or m.ω².y + m.ω².e = s.y Webthe whirling of shaft and its motion comes under the category of self-excited motion i.e. self-excited vibration in which the exciting forces and inducing motion are controlled by the motion itself. When the induced frequency matches with natural frequency, resonance will occur at certain speed, this speed is called as „critical speed‟. ... randy abbott 04/15/1966

http://www.freestudy.co.uk/dynamics/forced%20vibrations.pdf WebIf the shaft is out of balance, the resulting centrifugal force will induce the shaft to vibrate. When the shaft rotates at a speed equal to the natural frequency of transverse oscillations, this vibration becomes large and shows up as a whirling of the shaft. It also occurs at multiples of the resonant speed.
