wheel profile design should be able to resist wear and to allow stable vehicle running. The
ability to resist wear reduces the wheel reprofiling and replacement cost. The ability to allow
stable vehicle running is important for safety and ride quality.
In this work, a wear model based upon the work done in the wheel/rail contact patch is used
to predict wheel wear profiles. The effects of train dynamic response, random rail alignment
and the non-linearity of wheel/rail contact geometry are included
The distribution of contact patch work is obtained by discretized method and applied to the
wheel wear problem. Using the contact patch work wear model, consecutive wheel wear
profiles for tread contact and slight flange contact are predicted. These analytical wear
profiles match well with experimental results and other analytical approaches.
