摘　　要：采用近似方法模拟径向滑动轴承压力场分布。在轴承径向和周向以三角函数为基函数构造压力P的二维三角级数形式;应用迦辽金法,建立关于系数αij的线性非齐次代数方程组;采用Matlab软件解此方程组,得到各系数,进而得到近似油膜压力分布函数p(φ,z)。计算出各点压力值,绘制压力分布图像。The pressure distribution was simulated with a approximate method. Triangle function was used as basic function to construct the pressure P of two triangle series. With the use of the Kerlaojin method, some linearity inhomogeneous algebra equations about the coefficients αij were obtained. With the applivation of Matlab soffwane to solve the equations, the relative coefficients, the approximate distribution of fluid film＇s pressure p（φ,z） were determined. Using the primitive parameters, the value of pressure at every point was calculated, and the map of pressure distribution was drawn. Compared with ISO/DIS7902-2 it showed that the calculation accuracy is satisfied.
