摘　　要：从线接触乏油弹流润滑数学模型出发,以润滑油膜起始点位置为参数,根据接触区内流量连续条件,建立了点接触乏油弹流润滑的数学模型,运用多重网格方法和Matlab数值计算工具,对模型进行数值分析,根据分析结果总结了乏油弹流润滑的特点。The paper focuses on the solution of the numerical analysis for staved elastohydrodynamic lubrication （EHL） in point contacts. In the paper the numerical model of the staved EHL is established on the basic of the numerical model in line contacts, which thinks the position of the beginning point of the lubricant film as a parameter. The numerical calculation process is using Multi-grid methods and Matlab software tools.
