...Zeyuan Zhou; Hekun Jia; Bifeng Yin Purpose This paper aims to present a 3D static performance analysis model for the gas foil journal bearing to provide better understanding of the gas foil journal bearing and extend the development of the calculation about the static performance. Design...

... Double-layer bump foil Bearing stiffness Static performance As self-acting dynamic pressure gas foil bearings (GFBs) (Bruckner et al., 2005 ; Dellacorte et al., 2000 ; Heshmat et al., 2000) have the advantages of high precision, no pollution, simple maintenance...

...Chengjun Rong; Huaqi Lian; Yulong Li Purpose Oil-free heat pumps that use the system refrigerant gases as lubricants are preferred for thermal management in future space applications. This study aims to numerically and experimentally investigate the static performance of externally pressurized...

...Hongyang Hu; Ming Feng Purpose The purpose of this paper is to investigate the effect of the rounding in bump foil on the static performance of air foil journal bearings. Design/methodology/approach During the study, the bending moment of the new foil structure with rounding is proposed...

... that the structural parameters, the membrane center deformation and the inlet and outlet pressures of the piezoelectric membrane restrictor have an effect on the static performance of the restrictor. The identified flow rate result of the piezoelectric membrane restrictor is consistent with the models. Originality...
