分形理论在摩擦学研究中的应用

Application of Fractal Geometry in Tribology

  • 摘要: 采用尺度独立的分形参数可使粗糙表面和磨屑形貌的表征简单明了,并使表征具有唯一性,易于识别;基于分形参数所建立的摩擦学研究模型的预测结果可望不受测量仪器分辨率和取样长度的影响,因而比传统的基于统计分析的模型更为合理和有效。综述了分形几何在粗糙表面的表征,接触,磨损预测和摩擦温度分布以及磨屑定量分析等方面的应用现状和发展,指出了用分形理论研究摩擦学问题时应注意的着重点。

     

    Abstract: It is convenient and clear to characterize and identify rough surfaces and debris with fractal parameters of scale independence. The prediction results using fractal models of tribology would not change with the resolution of measuring instruments and the length of sample, so the models are more reasonable and effective than those based on statistical analysis. The current state and the development in the application of fractal geometry to the characterization, contact, wear prediction, frictional temperature distribution of rough surfaces, and debris analysis are reviewed. Several important issues about the application of fractal geometry in tribology are put forward.
