重载径向轴承三维弹性流体润滑的有限元和边界元耦合数值分析

NUMERICAL ANALYSIS OF THE FINITE ELEMENT AND THE BOUNDARY ELEMENT COUPLING OF THE THREE-DIMENSIONAL ELASTOHYDRODYNAMIC LUBRICATION FOR HEAVILY LOADED FINITE JOURNAL BEARINGS

  • 摘要: 本文采用有限元和边界元技术分析了重载径向轴承的三维弹性流体润滑(EHL)问题,并提出了一种精度高、收敛快的加权迭代计算模式,用该计算模式成功地求解了由二阶Reynolds方程、粘压方程和三维弹性方程组成的非线性方程组,得到了在各种大偏心率下轴承材料分别为钢、铜和巴氏合金的径向轴承的弹流静特性参数。

     

    Abstract: A coupling of the finite element and the boundary element methods is applied to the analysis of the three-dimensional elastohydrodynamiclubrication for heavilyloaded finite journal bearings. An iterative scheme, which is used to overcome the difficulty of the convergence at high eccentricity ratios, is provided in this paper. The scheme, which is called the weighted average method here, is successfully carried out in the iterative procedures of a set of non-linear equations that is constitutedby a two-dimensional Reynolds' equations, a viscocity-pressure equationand three dimensional elasticity equations, The analysis yields EHL static performance parameters of journal bearings under various high eccentricity rations, when bearing materials are steel, copper and bearing brass.
