摘　　要：Roynolds方程是滑动轴承油膜压力计算的基础,传统计算方法将轴承简化成无限宽或无限窄的一维形式,计算结果不符合实际情况。基于有限差分法,采用MATLAB软件编程计算,求解了完整的二维流动Roynolds方程,得到了滑动轴承油膜压力空间分布图。以此方法指导某水电站水轮机水润滑橡胶轴承改造为稀油润滑轴承的工作,取得了良好的效果。Roynolds equation is the foundation to calculate the oil film pressure of bearing.The bearing is simplified into a limitless wide or limitless narrow one-dimensional form for the traditional computing technology,the results of calculation do not meet the actual situation.The complete two-dimentional flow Roynolds equation was solved based on finite difference method and programming with MATLAB software,the film pressure distribution of sliding bearing was got.To guide the rebuilding of water lubrication rub...
