利用计算机图象技术,本文对铁谱技术进行了改进。用大小磨粒的真实面积和替代了光密度值。对磨粒形貌的数字特征采用了时间过程分析技术,实现了形貌描述的定量化。研究中发现拉缸前大小磨粒出现两极分化现象,其磨损不以切削为主。提出了新的磨合监测指标,采用散射度、欧拉数等特征参数对磨合过程进行了监测,在一定程度上提高了磨损监测的准确性。 The use of computer graphics technology, this paper on the iron spectrum technology has been improved. Use the true area of ​​the grain size and replace the optical density value. The digital features of the morphology of the abrasive particles were analyzed using the time-history technique to achieve the quantification of the morphology description. In the study, it was found that the size of abrasive grains in front of cylinder was polarized, and the wear was not mainly cutting. A new running-in monitoring index was proposed. The running-in process was monitored by the characteristic parameters of scattering degree and Euler number, which improved the accuracy of wear monitoring to a certain extent.
