磨粒分形维数与摩擦状态相关性的研究

以45钢-铜配副在浸油状态下进行磨损试验，考察了不同磨损阶段磨粒群体分形维数的分布特征，测量了多种磨粒表征参数，并就各表征参数与摩擦力的关联性进行了对比分析。结果表明：磨粒群体中轮廓分形维数的分布呈正态分布；磨粒分形维数相对于其他表征参数而言，和摩擦力相关性更大，且两者呈反比关系。

Study on Correlation between Fractal Dimension of Wear Particles and Friction State

The wear test of a brass ring against a steel ring was conducted in the 20# lubricating oil. The wear particles produced in different wear periods were analyzed by measuring system including optical microscope, pick-up camera and computer. Different characterization parameters of the wear particles were calculated. The results indicate that fractal dimensions of wear particles group present normal distribution and has a good correlation to the friction force comparing with other parameters. These results can be as information and helpful to the identification of wear states by study wear particles.
