...Yuanlong Cao; Kaiyuan Hao; Jiahui Fan; Hang Zhang; Hanqing Guan; Kai Feng Shape memory alloy (SMA)-gas foil bearings (SMA-GFBs) are novel gas bearings comprising top foil, SMA springs, and housing. The radial clearance, stiffness, and damping coefficients of SMA-GFBs can be regulated by the bearing...

.... Schematic view of bump-type foil bearings Accurate analytical models to predict the performance of gas foil bearings can release designers from the onerous task of investigating prototypes, which is time-consuming and expensive. Since the first theoretical model of bump foil bearing...

...Sébastien Le Lez; Mihai Arghir; Jean Frene The performance of gas foil bearings (GFBs) relies on a coupling between a thin gas film and an elastic structure with dissipative characteristics. Because of the mechanical complexity of the structure, the evaluation of its stiffness and damping is still...

...Tae Ho Kim; Luis San Andrés Commercial oil-free microturbomachinery implements gas foil bearings (GFBs) for reliable performance with improved efficiency. However, GFB modeling is still largely empirical, lacking experimental validation. An analysis of simple GFBs operating at large shaft speeds...
