摘　　要：为提高基于磨粒的机器状态监测的准确性,研究了磨粒特征随滑动磨损进程的变化规律。在球-盘磨损试验机上模拟可靠润滑和润滑不足2种工况下的摩擦磨损试验,分析了磨损过程中不同磨损阶段的磨粒尺寸分布和磨粒表面粗糙度,探讨了磨损进程中磨粒尺寸分布与磨粒表面粗糙度之间的关系。研究结果表明磨损进程中的磨粒特征的变化对机器状态监测极为有效。The evolutions of wear debris characteristics as wear progress in sliding wear process was studied.Sliding wear tests were conducted using a ball-on-disc tester under proper lubrication and improper lubrication conditions.The study of the particle size distribution and the surface roughness of wear particles in relation to the wear condition and the wear rates of the wear components were carried out.The results demonstrates that the wear debris characteristics offer valuable information for machine conditio...
