对于毛细管节流的动静压轴承，基于流量平衡方程和偏导形式的流量平衡方程，本文建立了油腔压力和油腔压力偏导的迭代准则和迭代公式。实践证明，该迭代方法具有物理意义明晰、迭代次数少和迭代适应性强的特点，可以显著提高毛细管节流的动静压轴承静动特性分析计算有限元程序的计算速度。 For the capillary throttled hydrostatic bearing, based on the flow balance equation and partial differential flow balance equation, the paper establishes the iterative criteria and iterative formulas for the pressure in the oil chamber and the partial pressure in the oil chamber. Practice has proved that the iterative method has the characteristics of clear physical meaning, less iteration and strong adaptability of iteration, which can significantly improve the static and dynamic pressure bearing performance of capillary throttling analysis and calculation of finite element program.
