Abstract
Wheel tread wear monitoring is great significance to ensure the safety of train operation. In view of the large amount of data in daily test of tread and the error easily occurred in manual analysis and processing, a solution of automatic processing of tread wear test tool based on MATLAB is proposed. The automatic tool first loads the test data of WPA + wheel profile measuring instrument, eliminates the data with large error, gives the index of wheel wear and generates a report; then according to the generated report, it gives the analysis data of wheel wear, and draws the comparison diagram between the measured tread profile and the standard one, and finally gives the wear analysis conclusion. At last, some test data are used to verify the effectiveness of the program.
