This paper desri an analytieal method for wheel wear prediction. The outputs from vehicle dynamic software are used to caculate the wheel wear. Two calculation examples are shown for a high-speed line and a conventional line. Through the comparison of two cases, we can see the wheel wear characteristics on the conventional line and the high-speed line. The conventional line has many curved tracks that cause severe wheel flange wear. The influences of curve radius on wheel wear are also described considering the operational perpormance of the high speed trainset. A method of calculation using contact patch work model is presented for determination of the evolution by wear of railway wheels.
