表面粗糙度几何特征的模糊聚类分析

Fuzzy Cluster Analysis of the Geometric Properties of Surface Roughness

本文用模糊聚类分析方法对表面粗糙度几何特征作了综合分析。指出现行评定参数R_a、R_z和S等仅仅各自反映表面轮廓的单一统计特征,只有综合评定才能反映表面的实际功能。文中给出粗糙度几何特征的聚类分析数学模式,可为粗糙度的综合评定提供理论依据。

In this article, the method of fuzzy cluster analysis is used to analyze the geometric properties of surface roughness compositely. The paper shows that the evaluated parameters presently used, such as R., R, and S, can only reflect the singular property of the surface profile individually, the composite evaluation can reflect the practical function of a surface. A mathematical model is given, which may offer a theoretical basis for the composite analysis of surface roughness.
