众所周知，工程表面由大量彼此叠加的粗糙度波长组成。提出了一种基于经验模态分解的表面形貌分析方法。该方法提供了良好的自适应分离的表面轮廓成多个波段。通过一个铣削工程曲面的应用实例，验证了经验模态分解方法在工程曲面分析中的可行性和适用性。
It is well known that an engineering surface is composed of a large number of wavelengths of roughness that are superimposed on each other. This paper proposes a new method for surface topography analysis based on empirical mode decomposition. The method provides good adaptive separation of surface profile into multiple bands. Applications are conducted by using a milled engineering surfaces to demonstrate the feasibility and applicability of the empirical mode decomposition method in the analysis of engineering surfaces.
