dcterms:description
The presented paper is focused on the static stiffness definition of fluid layer according to the number of Taylor vortices. There is a gap between two cylinders, where the inner one is rotating and axial flow is not assumed. The stiffness matrix as a function of angular speed is determined too. The fluid layer stiffness is specified for rotor in static balance and problem of damping is not considered. The Taylor vortices' influence is evident in the stiffness matrix, where all the elements are of the same orders of magnitude. In comparison with the stiffness matrix derived from the Reynolds equations, which has contrary the major diagonal elements lower by several orders of magnitude then the others, there is a marked difference. This theory will be used in new design of classical journal bearing using Taylor vortices principle.
