Abstract

The reported investigations aim at developing the theoretical model of a bearing characterized by variable geometry. The method used for calculating the non-linear response to an arbitrary excitation takes into account factors characteristic of the variable bearing geometry, including friction in the supports. The article presents part of the study referring to numerical analyses oriented towards developing the model of a high-speed rotor supported on bump-foil or tilting pad bearings.
