CFD models assess loading performance in radial bearings, suggesting designs to improve stability and accuracy.

The study aims to evaluate the hydrodynamic effects and loading performance of partial-arc aerostatic radial bearings under high-speed conditions.
Developed a CFD-based hydrodynamic model for gas-film flow in partial-arc aerostatic radial bearings.
Investigated the impacts of geometric parameters like chamber configuration and eccentricity on loading.
Analyzed the influence of high-speed rotation on loading force stability and stiffness-testing accuracy.
The proposed bearing design effectively suppresses hydrodynamic effects.
Improved loading force stability and enhanced stiffness-testing accuracy were observed.
