Tilting-pad journal bearings are widely used in industry to support rotating shafts due their high dynamic performance. The operating limits of these mainly represented by the maximum permissible temperature lined materials pads and minimum thickness oil-film under which mixed lubrication can occur. current trend bearing development sees adoption innovative production pads, that provide higher ...

It has been shown that ultrasonic techniques work well for online measuring of circumferential oil film thickness profile in journal bearings; unfortunately, they can be limited by their range and unable to capture details the all around bearing circumference. Attempts model over full rely on deterministic approaches, which assume observations true with absolute certainty. Unaccounted uncertain...

Abstract Rotating machinery supported on journal bearings is affected by forces due to rotating unbalance and pressure gradients in the oil film. The interaction of these can evoke nonlinear behaviour, including asynchronous motion even chaos. This work attempts characterise sub-synchronous rigid rotor cylindrical abovementioned interaction. analysis focuses behaviour at speeds lower than thres...

Journal bearings are the most common type of in which a shaft freely rotates metallic sleeve. They find lot applications industry, especially where extremely high loads involved. Proper analysis various bearing faults and predicting modes failure beforehand essential to increase working life bearing. In current study, vibration data journal healthy condition five different fault conditions coll...
