| 摘 要： |
An in-depth study of friction and wear requires analysis of the surface morphologies and contact status of friction pairs in mechanical systems. The bearing area curve is introduced for the calculation of wear, and combined with the concept of repositioning. The application of fast calculation of wear amount and improved three-dimensional characterization of a bearing area curve is achieved by this new method. The best roughness surface is used as the target surface to extract the target bearing area curve. The influence of microtexture parameters on the bearing area curve is studied to determine the optimal microtexture parameters. The test results show that a matching texture surface has a short run-in time and the lowest friction coefficient after stabilization among the surfaces studied herein, and the presence of a texture changes the wear mechanism from the original adhesive wear to abrasive wear and improves the tribological performance. The best texture parameters and laser process parameters are determined, which provide new ideas for the optimal design of surface topography.
对摩擦与磨损的深入研究需要分析机械系统中摩擦副的表面形貌和接触状态。本文引入了轴承区域曲线用于磨损计算，并结合了重新定位的概念。通过该新方法，实现了磨损量的快速计算以及轴承区域曲线三维特性的提升。以最佳粗糙度表面为目标面，提取目标轴承区域曲线，并研究微观纹理参数对轴承区域曲线的影响，以确定最优的微观纹理参数。测试结果表明，在所研究的各表面中，匹配纹理的表面具有最短的运行时间，且在稳定后摩擦系数最低； 纹理的存在使磨损机制从原来的粘着磨损转变为磨料磨损，从而改善了摩擦学性能。最终确定了最佳纹理参数和激光加工工艺参数，为表面拓扑结构的优化设计提供了新的思路。 |
