Vibrational Diagnostics of Rotating Machinery Malfunctions
International Journal of Rotating Machinery, 1995 This paper outlines rotating machinery malfunction diagnostics using vibration data in correlation with operational process data. The advantages of vibration monitoring systems as a part of preventive/predictive maintenance programs are emphasized. After

Laser anemometer measurements in a transonic axial-flow fan rotor [PDF]
, 1989 Laser anemometer surveys were made of the 3-D flow field in NASA rotor 67, a low aspect ratio transonic axial-flow fan rotor. The test rotor has a tip relative Mach number of 1.38.

Generalized vortex-model for the inverse cascade of two-dimensional turbulence
, 2013 We generalize Kirchhoff's point vortex model of two-dimensional fluid motion to a rotor model which exhibits an inverse cascade by the formation of rotor clusters.

Natural Frequency of Rotor with Rotor Core.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991 A rotor core of induction motors consists of many multilayered steel sheets for core which are fixed to a shaft with a shrinkage fit. A bending vibration of rotors with such a rotor core is investigated experimentally. It is shown that the rotor can be modelized by an opening of the multilayered steel sheets and a equivalent Young's modulus of the ...

Development of flexible rotor balancing criteria [PDF]
Several studies in which analytical procedures were used to obtain balancing criteria for flexible rotors are described. General response data for a uniform rotor in damped flexible supports were first obtained for plain cylindrical bearings, tilting pad

Modeling and analysis for surface texturing on soft sliders in mixed lubrication
FrictionExperiments have shown that surface texturing can enhance the tribological properties of bearings and seals made of soft materials such as polymers. However, the underlying mechanisms are still not fully understood and lack theoretical research.
