The effects of a membrane restrictorâ??s design parameters on the performance of a hydrostatic\nopposed-pad bearing are presented in this article. Compared to the single-pad bearing, the opposed-pad\nbearing can perform much better in terms of static stiffness over a wider load range. It is also found\nthat, for small bearing eccentricity, the optimal design restriction ratio of 0.25 still results in high\nbearing stiffness even if the dimensionless stiffness of membrane is not the optimal value of 1.33.\nFurthermore, decreasing the ratio of the upper effective area to the lower effective area generally\nincreases the applicable working range of the bearing. Additionally, for high loading demands,\nthe chance for further improvement of bearing performance by employing different design parameter\nfor each pad is examined. Finally, a design procedure for designing the membrane restrictor for\nan opposed-pad bearing to achieve high static stiffness is given.
