摘要
基于高温发汗自润滑材料微观结构特征及销-盘摩擦学试验结果,分析了该类材料摩擦过程中摩擦表面的动态演化机理,并在此基础上采用元胞自动机方法建立了该类材料的摩擦过程动态特征预测模型。利用所建立的模型对其摩擦过程中的摩擦因数、摩擦表面形貌及摩擦表面润滑剂分布进行了模拟研究。模拟结果和摩擦学试验结果具有良好的一致性。研究结果可为高温发汗自润滑材料的摩擦学设计提供理论指导。
The dynamic evolution mechanism on a friction surface of high temperature gland self-lubricating composite was analyzed based on the micro-structure characteristics of the materials and its tribological experimental results in the pin-disk test.A cellular automaton model to describe the dynamic characteristics of the friction process was developed and used to study the friction coefficient and the topography as well the lubricants distribution on the worn surface in the sliding.The agreement between the simulation and experimental results show the model is available and can be used to optimal design of the materials.
