摘　　要：综合多数供气孔静压环形止推气体轴承和多槽式表面节流气体润滑轴承结构和特性,采用非结构网格建立气膜模型,选取合适的边界条件和初始条件,并用基于有限体积法的F luent软件进行迭代计算,得出其数值结果。Structures and characteristics of multi - row pressure inlet holes footstep air bearing and multi - groove surface restriction gas lubricated air bearing were analyzed, gas film model was set up by non - structural grids and corresponding boundary conditions as well as initialization conditions were chosen, and numerical results were got by iterative calculating using Fluent software.
