重载滑动轴承非牛顿流体的三维弹性流体动力润滑分析的加权平均法

The Weighted Average Method inAnaiysis of Three-DimensionalElastohydrodynamic Lubrication for Heavily-LoadedJournal Bearings and Non-Newtonian Fluids

本文采用加权平均法成功地求解了由广义Ｒｅｙｎｏｌｄｓ方程（幂次型）和三维弹性方程组成的非牛顿体弹流模型，该方法较好的解决了大偏心率下的弹流迭代收敛困难的问题。该方法具有收敛快，对初值要求松且计算精度高等优点，是一种解决弹流问题较好的迭代模式。

The paper has successfully solvcd non-Newtonian elastohydrodynamic model composed of thegeneralized Reynolds equation (power-law) and three dimensional elastic equation employing Weight-ed Average Method, which can be used to effectively overcome the difficulty in the convergence of e-lastohydrodynamic iteration at high eccentricity rations. The method, with the advantages of morequick convergence, higher accuracy and lower intial value requirement,is a better iteration model todeal with elastohydrodynamic problems.
