On numerical analysis of railway vehicle dynamics, the contact position between wheel and rail is a necessary parameter to calculate creep forces or contact pressures etc., and it is generally calculated by geometric methods without considering wheelset flexibility, which would influence on the contact position. This article presents an experiment to measure bending of a real wheelset according to loads on the axle boxes of the wheelset rolling on a roller rig. Results of the experiment show that the wheelset bends of its center upward, and as far as the loads correspond to the loads of commuter cars, the wheelset bending changes linearly, when the contact point between wheel and rail is on wheel tread. And a geometric calculation with the results derives the shift of the contact position toward the field corner of the rail.
