多重网格法求解线接触弹流问题

Solutions of the elastohydrodynamic lubrication line contact problems with multigrid method

详细介绍了利用多重网格法求解弹性流体动压润滑的线接触问题的方法；提出了选择载荷迭代松弛因子和确定不同迭代区域划分的改进方法。通过与其它解法和经验公式结果的对比表明：多重网格法不仅是可行的而且具有计算速度快、收敛稳定性好等优点。

The EHL line contact problems solved with multigrid method are introduced in detail. New methods to determine the load balance coefficient and to divide different iteration regions are proposed in the present paper. Comparisons of present results with the results from Newton-Ra- phson method and the empirical formula are carried out. It shows that the multigrid method is not only feasible but with steady convergent ability and fast computation speed.
