首次将多尺度理论应用于三维表面形貌表征,采用不同的观察尺度对原始表面进行最小二乘、Motif法过滤,得到多尺度基面和多尺度表面,并基于WM函数进行图形、粗糙度参数表征研究。研究发现:多尺度理论的应用可以将形状偏差和波纹度视为某相对较大观测尺度下的粗糙度,并成功定量过滤,从而有效地解决传统粗糙度表征中形状偏差和波纹度的影响,提供一种契实可行的用于表征表面形貌和评定表面功能的理论或方法,更加准确地表达三维表面特性与其表面形貌参数的基本关系。
For the first time, the multi-scale theory is applied to the three-dimensional surface topography. The original surface is filtered by least squares and Motif method using different observation scales to obtain multi-scale base and multi-scale surfaces. Based on the WM function, the shape and roughness parameters Characterization research. The results show that the application of multiscale theory can take the shape deviation and waviness as the roughness under a relatively large observation scale and successfully quantitatively filter so as to effectively solve the influence of shape deviation and waviness in the traditional roughness characterization. To provide a realistic theory or method for characterizing surface topography and evaluating surface function, and to provide a more accurate representation of the basic relationship between the three-dimensional surface properties and the surface topography parameters.
