论文摘要
在摩擦学中,正确表征粗糙表面的地形是很重要的。在这项工作中,通过白光干涉仪测量了普通研磨表面的三维构图,并分析了它们的几何统计特征。人们注意到,只有当总测量区域大于阈值大于阈值时,统计表征是合理且稳定的,应在实际测量中牢记。对于各种普通的磨削表面,Asberity-Summit的高度遵守高斯分布,等效曲率半径遵循修饰的F-分布。这些统计特征有助于分析粗糙表面的接触和摩擦行为。
In tribology, it is of importance to properly characterize the topography of rough surfaces. In this work, the three-dimensional topographies of plain grinding surfaces are measured through a white light interferometer, and their geometrical statistical features are analyzed. It is noticed that only when the total measured area is larger than a threshold value, is the statistical characterization reasonable and stable, which should be kept in mind in actual measurements. For various plain grinding surfaces, the height of asperity-summit obeys a Gaussian distribution, and the equivalent curvature radius follows a modified F-distribution. These statistical characteristics are helpful to analyze the contact and friction behaviors of rough surfaces.
