| 摘 要： | 利用多重网格算法，在最粗网格上，采用Newton-Raphson迭代法模式精解线接触弹流非线性方程组，充分利用了多重网格法与Newton-Raphson法各自的优点，计算实践表明，求解弹流问题的数值解过程在收敛与稳定性方面均有较大改善，且有相当宽的载荷参数适用范围。

| Abstract: | In this paper, the nonlinear equations of the EHL problems is accurately solved by multigrid and Newton Raphson method in the coarsest grid, which completely makes use of themselves advantages of multigrid and Newton Raphson method. The fact shows that the algorithm process of solved EHL problems had been improved greatly in convergence and stability and the suitable extend of load variable is broad. |
