...Hongyang Hu; Huijun Wu; Jichao Wang; Jiamin Liu Purpose To enhance the load capacity and dynamic characteristics of gas foil conical bearings (GFCBs), two kinds of microgrooves (sector and Fibonacci-like shape) are arranged on the top foil surface. Design/methodology/approach The Reynolds...

... iterative method on the staggered grid to obtain the thickness and the pressure distribution of the oil film. The radial and axial load capacities of SHSBs are determined by the pressure field integration over the spherical surface. Findings The results show that the parameters such as oil supply...
