In order to study the effect of inclination status on the performance of porous aerostatic journal bearing,the porous air journal bearing was numerically analyzed with the finite element method based on 1D flow model.The related factors affecting the static performance of porous air bearings,such as the permeability of the porous material,the eccentricity and the inclination angle,were analyzed.The results show that the initial eccentricity has a great influence on the load capacity.The load capacity of the porous air journal bearing will increase by increasing inclination angle under the same initial eccentricity,and will also increase by increasing initial eccentricity and the permeability at the same inclination angle.The larger the initial eccentricity,the greater influence of permeability on load capacity.
