| 摘 要： | 该文基于分形几何理论研究了表面形貌的分形特征,用结构函数法计算表面轮廓的分形维数,用Taylorsurf-6型轮廓仪对磨损前和磨损后的缸套内腔表面轮廓进行测量.分形分析结果表明,缸套内腔表面具有多重分形特征,其临界波长的大小与珩磨时的磨粒直径相对应.

| Abstract: | Based
on the fractal geometry theory, the fractal cha racterizations of surface topography are
studied. The fractal dimension of profi le is calculated by structure function method. The
surface profiles of cylinder bore before and after wear are measured by use of
Taylorsurf-6 Profilemeter. Th e fractal analysis shows that the cylinder bore surface is
multifractal,and the transition wavelength corrsponds to the diameter of the abrasive
particles. |
