The highspeed wheel/rail steady rolling contact finite element model was established by using the mixed Eulerian/Lagrangian method and the friction coefficient prediction model considering the influence of temperature and humidity.Without considering transverse and angle of attack,the contact characteristics and wear characteristics of XP55,S1002 and LMa wheel profile when contacted with CHN60 rail were compared and analyzed.A highspeed train wheel profile which is most suitable for hot and humid regions was selected.Results show that XP55 wheel profile has the best profile traction performance and wheels recovery performance,but the poorest wear resistance and critical speed.S1002 wheel profile has the best wear resistance and critical speed,but the poorest matching performance with CHN60 rail,the worst traction performance and wheels recovery performance.The contact characteristics and wear characteristics of XP55 between XP55 wheel profile and S1002 wheel profile,which is more suitable for the wheel profile of high speed train under the hot and humid regions.
