摘要
有限差分法是一种求解滑动轴承二维雷诺方程的有效方法,但是有限差分法使用的是单纯的超松弛迭代法求解雷诺方程。介绍了用多重网络法求解雷诺方程,它是加速后的超松弛迭代方法,比单纯的超松弛迭代法具有更短的计算时间、更高的计算精度和更快的收敛速度。
Finite difference method is a very effective method for solving the two-dimensional Reynolds equation of sliding bearing. However, the finite difference method makes use of simply over-relaxation iterative method to solve the Reynolds equation, the multi-grid method introduced in this paper is an accelerated over-relaxation iterative method with shorter computation time, higher precision and faster convergence rate than finite difference method. This paper described how to use the multi-grid method to solve Reynolds equation, and gave a concrete example.
