.... Simulation of the gas bearing interface was provided by a large scale code developed by the author. The computational requirements consisted primarily of first creating the equilibrium (steady-state) solution of the opposed sliders and foil disk, followed by numerically tracking the dynamic response...

...M. Amine Hassini; Mihai Arghir The traditional small perturbation method is successfully used for linear dynamic analysis of gas bearings but excludes any nonlinear study. Investigating large displacements requires the evaluation of the nonlinear aerodynamic forces in the thin film. To avoid...

...Yang Lihua; Qi Shemiao; Yu Lie Although gas-lubricated tilting-pad bearings are widely used in high-speed turbomachinery, the theoretical prediction of the dynamic characteristics of tilting-pad gas bearings is also a very difficult problem because of its structural complexity. Several approaches...
