摘　　要：介绍一种自动检测铁路车辆轮对踏面擦伤及剥离的新方法.该方法用激光位移传感器获得踏面数据,通过纠偏、插值和运用经典的数据处理的中值滤波和边界搜索等方法对数据进行分析;通过对数据矩阵进行数字化处理,得到了轮对踏面损伤结果.运用VC++和Matlab语言编制出通用分析软件,功能包括轮对踏面的二维和三维图形显示、打印踏面擦伤和剥离的损伤尺寸等.A novel method for automatically detecting the scrape and exfoliation of train wheelset tread surfaces was proposed. In this method, data on train wheelset tread surfaces are gained by using laser displacement sensors, and analyzed through deviation rectifying, interpolation and multistage median filtering. The digital matrix for the tread surfaces is digitized so as to gain their status. A universal software for the measuring system was developed with VC++ and Matlab programming languages. This software can automatically show 2- and 3-D views of train wheelset tread surfaces, and print the image of scrape and exfoliation areas.
