Experimental study of coupled shaft bending - blade umbrella mode vibration of a turbine rotor model
Nihon Kikai Gakkai ronbunshu, 2014 This paper describes an experimental study on the characteristics of blade-shaft coupled bending vibration of a rotor system with a bladed disk. In a rotor with relatively long blades such as low-pressure steam turbines, the coupled vibration of shaft ...

Solid Body Rotation Vibration [PDF]
International Frontier Science Letters, 2014 For solid body rotation of an incompressible fluid inside a vertical cylinder (open to air at the top with gravity acting down) it is proposed that if a small piece of fluid is displaced horizontally and radially by a short distance and then released, it will oscillate with a constant frequency as viewed in the rotating frame of reference.

On the Vibrations of the Shaft Carrying an Unsymmetrical Rotating Body
Transactions of the Japan Society of Mechanical Engineers, 1962 The authors named the rotor having two unequal principal moments of inertia except the polar moment of inertia, "asymmetrical rotor", and studied the vibratory characteristics of the motions of the shaft carrying an asymmetrical rotor analytically and experimentally.
