Effects of Key Factors on Load-carrying Capacity of Radial Static Air Bearing
Based on the momentum conservation equation and conservation equation, the analysis model is established for a radial static bearing lubricated by the air in composite spindle. The finite element model of the radial static bearing b built by nsing the finite element software, and the simulation analysis U carried out The effects of eccentricity, orifice diameter, supply pressure and rotational speed on the Load-carrying capacity are simulated and analyzed under different boundary conditions. The results show the Load-carrying capacity increase with the increase of the eccentricity and supply pressure. There is an optimal orifice diameter for the largest Load-carrying capacity under the invariable air membrane thickness. Due to the increase of dynamic pressure effect, the Load-carrying capacity increase with the increase of rotational speed. These results are helpful to designing the optimal radial static bearing.
