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”. If the frequency of rotation is equal to one of the resonant frequencies … See more Dunkerley's method is used in mechanical engineering to determine the critical speed of a shaft-rotor system.

WebEXPERIMENT NO. 5 – WHIRLING OF SHAFT OBJECTIVE: After completing this experiment student should be able to Understand the concept of critical speed of … WebSep 12, 2024 · ω = Angular velocity of the shaft. 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
