摘　　要：采用有限差分法计算轴向槽圆柱气体动压轴承的压力分布,计算轴承的承载能力和偏位角。分析显示,轴向槽位置对轴承性能有较大影响。通过计算结果与相关文献的相应数据进行对比证明,该计算方法的可行性。Finite difference method has been employed in computing pressure distribution for axial-grooved cylindrical gas-lubricated dynamic bearing. The load capacity and the attitude angle for the bearing have been obtained. The numerical results show that the influence of the location for the axial groove on the characteristics for the bearing is evident. The results of some examples have been compared with the literatures, and the feasibility of the numerical method presented has been verified.
