Abstract:

A new-type of gas lubricated foil thrust bearing, with characteristics of simplicity and stability, is presented together with its theoretical analysis in this paper. By coupling the compressible, two-dimensional equations for gas lubrication with the deformation equations for an elastic piate, the gas film thickness and pressure distribution of the bearing are computed using an isoparametric finite element method. Bearing testings reveal that this new-type of bearing can run normally at high speed under certain loadings.
