In this work, to improve the static behavior of aerostatic journal bearings, we examine the effect of pockets with different shapes, including the square, rectangular 1, rectangular 2, and circular, manufactured on the surface of the aerostatic journal bearing. The effects of the pocket shapes, pocket area $\overline{S}$, eccentricity ratio ɛ, orifice diameter d_f, average gas film thickness h₀, and misalignment angles ${\phi }_x$ and ${\phi }_y$ on the static performance are investigated using simulations. The Reynolds equation is solved by the finite-element method in this work. Simulations reveal that the pocket area $\overline{S}$, eccentricity ratio ɛ, gas film thickness h₀, orifice diameter d_f, and misalignment angles ${\phi }_x$ and ${\phi }_y$ have a significant influence on the load force F and the stiffness K. In general, rectangular 2 pocket bearings are found to perform somewhat better than bearings with other pocket shapes, with the pocket depth set to one-half of h₀, when the pocket area $\overline{S}$ varies from one-twelfth to one. The pocket area $\overline{S}$ should be set according to the average gas film thickness h₀ and the orifice diameter d_f to achieve a better static performance for the bearings. For bearings operated with misalignment angles ${\phi }_x$ and ${\phi }_y$, different pocket areas $\overline{S}$ should be set according to the pocket shapes for the optimal design.

在这项工作中，为了改善空气静压轴承的静态性能，我们研究了在空气静压轴承表面上制造的不同形状的凹穴的影响，包括方形，矩形1，矩形2和圆形。口袋形状，口袋面积的影响$\overline{\mathrm{小号}}$，偏心率ɛ，孔直径d _f，平均气膜厚度h ₀和偏心角${\phi }_X$ 和 ${\phi }_{ÿ}$通过仿真研究静态性能。在这项工作中，雷诺方程是通过有限元法求解的。模拟显示口袋区域$\overline{\mathrm{小号}}$，偏心率ɛ，气膜厚度h ₀，孔直径d _f和偏心角${\phi }_X$ 和 ${\phi }_{ÿ}$对负载力F和刚度K有重要影响。通常，发现矩形2凹窝轴承的性能要好于其他凹腔形状的轴承，当凹窝面积设为h ₀时，凹窝深度应设为h ₀的一半$\overline{\mathrm{小号}}$从十二分之一到一。口袋区域$\overline{\mathrm{小号}}$应根据平均气膜厚度h ₀和孔口直径d _f进行设置，以使轴承具有更好的静态性能。用于偏心角轴承${\phi }_X$ 和 ${\phi }_{ÿ}$，不同的口袋区域 $\overline{\mathrm{小号}}$ 应根据口袋形状进行设置，以实现最佳设计。
