摘　　要：为研究轴承钢球展开轮表面微结构主要参数(面积、形状、深度)对干摩擦条件下展开轮磨损量的影响,采用正交试验法对不同参数的微结构表面进行试验,应用仿真软件进行应力分析,得到不同几何参数微结构的微观应力分布状态,结合试验与应力分析的结果对Archard磨损模型进行修正。结果表明:减磨效果最好的是菱形微结构,单坑面积为3.14×10^(-2) mm^(2),深度为150μm。发现不同几何参数微结构的高应力区分布位置,推导出包含微结构主要参数变量的磨损量计算模型,可为微结构展开轮的设计及寿命预测提供理论依据。In order to study the dry friction wear relationship between the bearing steel ball unfolding wheel with the surface microstructure parameters(area,shape and depth),the orthogonal test method was used to test the microstructure with different parameters.The simulation software was used to analyze the stress.The stress distribution of the microstructure with different parameters is obtained.The Archard wear model was modified by combining the results of tests and stress analysis.The results show that the microstructural parameters with the best wear reduction effect in the experimental range were the diamond microstructures with an area of 3.14×10^(-2) mm^(2) and a depth of 150μm.The distribution locations of high stress zones in microstructures with different geometric parameters are found.The wear calculation model containing the parameters of the microstructure is derived.It can provide theoretical basis for the design and life prediction of the microstructure unfolding wheel.
