Lambda比，即滚动轴承内润滑油膜厚度除以复合材料粗糙度，已被公认为与轴承性能（主要是疲劳寿命）相关的重要接触参数超过25年。本文考虑了一种简化的轴承接触内功能过滤方法，该方法为更大范围的轴承尺寸和载荷提供了更合适的复合粗糙度。用一系列标准和修正lambda比率的回归模型（包括不耦合的lambda参数）对这一概念进行了检验。使用三种不同的统计指标对模型进行评级，以评估每个模型如何解释大量轴承测试数据中存在的变化。于1989年10月16-19日在佛罗里达州劳德代尔堡举行的第35届STLE/ASME摩擦学会议上发表
Lambda ratio, the lubricant film thickness divided by the composite roughness within an operating rolling element bearing, has been recognized for more than 25 years as an important contact parameter related to bearing performance, primarily fatigue life. This paper considers a simplified method of functional filtering within a bearing contact that provides a more appropriate composite roughness for a wider range of bearing sizes and loadings. The concept was tested with a series of regression models of standard and modified lambda ratios, including the uncoupled lambda parameters. The models were rated using three different statistical indices to assess how each model accounted for the variation present in a large collection of bearing test data.
