A wheel/rail contact and wear model are established with the China existing railway track parameters. The wear performance of wheel LM matching rail R60 and R75 is compared with each other. According to the numerical results, the rail R75 contact patches is distributed in rail gauge, corner, and top areas centrally, and the contact lines are not continuous. When the wheelset lateral displacement less than 3 mm, the rolling radius and contact angle difference of the two pair wheel rail match are almost the s...
