The Generation and Transmission of Vibration in Plain Cylindrical Bearings. Part 2. Experiment.
Abstract
The vibration transmission characteristics of hydrodyynamic bearings have been investigated at frequencies well above the out of balance frequency. Part 1 of this report developed theories to predict the linear transfer functions of bearings and to examine the effects of non linearities in modulating the response to external forces. This part of the report describes an experimental investigation on a bearing test rig aimed at validating the theories. It is concluded that: (1) bearings are not always rigid to vibration, the frequency range over which the rigidity applies being determined by the bearing parameters; (2) Transfer functions across the bearing in the direction of the applied force are reciprocal; and (3) The bearing can introduce modulation in the response to a single-frequency force.
