Abstract
The rolling-stocks on conventional line have suffered wheel problems due to the incompatibility between wheel and track condition. Especially, The 1:40 coned wheel profile's wear is very severe and these increase wheel maintenance cost. Thus we designed several arc-type wheel profiles coned 1:/20 to reduce the wheel flange wear and analyzed the dynamic performance of designed profiles. Tests carried out in service line to analyse the dynamic performance and verify the wear reduction for two cases of profiles. Test results shows the equal level of dynamic performance and the improvement of wheel flange wear compared with the conical wheel profile coned 1:40.
