This paper examines finitie element models for studying of the frictional heating of rolling stock wheel by wheel tread braking. The Main purpose of this study is to obtain the thermal stress distribution in wheel. CFD(Compter aided Fluid Dynamic)analysis is performed to obtained reliable heat convection coefficients in wheel surface. Heat convection coefficients from CFD analysis is compared with reference data. Various thermal loading case is investigated and fluctuating heat flux is calculated by considering actual operation condition of wheel. Finite element method is adopted to ged temperature distribution and thermal stress distribution in wheel with linear analysis.<br/>
