本文系统地阐述了表面纹路评定的各个方面,举例说明了表面纹路对摩擦、摩损和润滑作用以及对摩擦副承载能力,抗胶合能力的影响,指出了目前评定表面纹路国家标准所存在的问题,提出了能全面反映纹路特征的三个统计函数作为评定指标,即表面轮廓的中线平均值,概率分布函数和自相关函数。 This paper systematically expounds various aspects of surface texture evaluation, and illustrates the effect of surface texture on friction, wear and lubrication as well as the bearing capacity and anti-gluing ability of the friction pair, and points out the problems existing in the current national standards for surface texture evaluation , Three statistical functions that can fully reflect the features of the lines are proposed as the evaluation indexes, that is, the average of the median of the surface profile, the probability distribution function and the autocorrelation function.
