| 摘 要： | 提出了一种间隙函数是二维变化的薄油膜润滑数值计算方法，通过该方法计算了平行平板中凸起物对油膜压力分布的影响，结果表明：当宽径比为0.5～1.5并对滑动轴承进行动压计算时，把间隙函数考虑为一维函数会造成一定的误差。

| Abstract: | This paper presents a new numerical method for studying the effect of thin film thickness changing in two dimensions in lubricating flow past protuberances shaped either like circular disk with parallel surfaces or like spherical segments. By using this method, the differencs of results for pressure distributions between film thickness changing in two dimensions and in one dimension can he considered. |
