Abstract:Some intercity lines suffered from abnormal rapid wheel flange wear, which not only caused frequent wheel re-profile, but also lead early scrapping of wheelsets, greatly increased the operation cost and affecting the operation order. In order to analyze the cause of abnormal wheel flange wear, the abnormal wear of wheel rail on intercity railway had investigated and tested, taking the measured wheel rail profile as the input, the mechanism of wheel flange abnormal wear was studied by using geometric matching, wheel rail contact analysis and other methods, and the control measures of wheel flange wear were studied through field test and simulation analysis. It is indicate that the rail head profile is seriously weakened and deviates from the design rail profile of small curve rail profile of individual lines in the long-term operation, the wheel and rail profile do not match and lead the wheel flange appears rapid wear, moreover, the profile of wheel flange is gradually close to that of severely worn rail and forming conformal wear. In order to reduce the wheel flange wear rate of the intercity EMU, it is suggested that priority should be given to rail grinding to restore rail design profile and wheel/rail lubrication measures;Next adopt regular turn around operation, wheel and rail profile optimization and other measures.
