... helium film, causing the side-0 slider to react. The disk serves to pass the energy of the shock back and forth between the two gas bearing assemblies without contact, with the only damping (of this analysis) being created by the viscosity of the two helium films. Coupling of the slider modes...

...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...

... air bearing gas bearing iterative method Simulation of an air- or gas-lubricated bearing requires the solution of compressible-fluid Reynolds equation. Due to the lack of analytical solution Reynolds equation is usually solved numerically after the equation is discretized. The discretized...

...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...
