In the theoretical analysis, three systems were identified: a rotor, a gas film and a exible structure. The mathematical analysis involves formulation of analytical equations for each of these elements and determination ...

Air-foil technology is an interesting alternative for classic rolling or oil bearings in turbomachinery. It ensures low power losses, do not require external lubrication or pressurization and is capable of working with ...

The work is devoted to an analysis of the journal bearing dynamics employing a numerical model which takes into account factors related to motion and friction of non{rotating elements of the sleeve. This model yields the ...
