摘　　要：以连杆衬套表面形貌为研究对象,对采集来的表面形貌数据根据波长不同,利用小波函数将其分解成低频和高频信号。其中低频信号代表表面粗糙度评定的基准面,高频信号代表表面粗糙度。然后重构出表面粗糙度。该方法可以较为精确地评定零件的表面粗糙度。Regard the surface wavelet function, the collected frequency signals according to morphology of connecting rod bushing as the research object, using surface topography data can be decomposed into low frequency and high different wavelength. The low frequency signals representing the surface roughness evaluation datum , high frequency signals representing the surface roughness. And then reconstruct the surface roughness. This method can assess the surface roughness of the parts more accurately.

关 键 词：连杆衬套 小波函数 表面粗糙度
