Abstract：In the actual running operation, left and right wheels wear unevenly will cause wheel/rail asymmetric contact, which influences the dynamic behaviors of railway vehicles seriously. This paper elaborated the principle of the affect of wheel movement which caused by shape change of the tread. Build up EMU dynamic simulation model combined with the measured wheel tread wear data, and analysis the dynamic behaviors of different wear conditions.The results show that with the intensification of the wheel tread wear, the stability, riding quality, derailment coefficient, wheel axle lateral force, friction power and axle box lateral acceleration are all getting poor.
