在论文中，基于一系列实验和自润滑机制分析，采用元胞自动机方法建立了一个三维模型。该模型用于研究高温滑动过程中汗液自润滑复合材料的动态摩擦过程。利用元胞自动机（CA）模型计算出了复合材料的滑动摩擦系数以及磨损表面上润滑剂的分布。计算结果与实验结果的一致性表明，论文中所建立的模型可有效地用于研究汗液自润滑复合材料在高温下的摩擦行为。
In the paper, a three-dimensional model is developed with cellular automaton method based on a series of experiments and the self-lubricating mechanism analysis. The model is used to investigate the dynamic friction process of sweat self-lubricating composite during high temperature sliding. The sliding friction coefficient and the distribution of lubricant on the worn surface of the composite are calculated out by using the cellular automaton (CA) model. The agreement between the computing and experimental results shows the model developed in the paper can be effectively used to study the friction behaviors of the sweat self-lubricating composite at high temperature.
