In the current study, we propose a bifractal stratified characterization method to evaluate the surface profile evolution of a plateau honing cylinder liner during the wear process. This method is suitable for the characterization of two-process and worn surface profiles with bifractal and stratified characteristics. We develop a bifractal truncated separation structure function method to calculate the characterization parameters of the proposed method. In particular, the upper- and lower-strata surface profiles are truncated and separated in order to calculate their fractal parameters. Experimental results demonstrate the ability of the proposed method to outperform the traditional fractal method in characterizing the evolution of the plateau honing cylinder liner surface profile during the wearing process.

高原珩磨缸套在磨损过程中表面轮廓的双分形分层表征

在目前的研究中，我们提出了一种双分形分层表征方法来评估高原珩磨缸套在磨损过程中的表面轮廓演变。该方法适用于表征具有双分形和分层特征的双过程和磨损表面轮廓。我们开发了一种双分形截断分离结构函数方法来计算所提出方法的表征参数。特别是，为了计算它们的分形参数，上层和下层地表剖面被截断和分离。实验结果表明，该方法在表征磨损过程中高原珩磨缸套表面轮廓的演变方面优于传统的分形方法。
