Finite element analysis of misaligned rotors on oil-film bearings

On the Characteristics of Misaligned Journal Bearings

Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...

Computational Analysis of Gas Foil Bearings Integrating 1D and 2D Finite Element Models for Top Foil

Gas foil bearings (GFBs) are finding widespread usage in oil-free turbo expanders, APUs and micro gas turbines for distributed power due to their low drag friction and ability to tolerate high level vibrations, including transient rubs and severe misalignment, static and dynamic. The static load capacity and dynamic forced performance of GFBs depends largely on the material properties of the su...
