Abstract
The effects of four factors on the fatigue strength of 160km/h high speed freight car wheel web were studied by FE technique according to Standards UIC 510-5. The four factors were tread wear, shrinkage of the wheel onto the axle, wheel rotation speed and wheel-rail dynamic load coefficients. The results indicate that shrinkage and wheel rotation speed have no effect on the range of dynamic stresses of critical region on the wheel web; Tread wear and wheel-rail vertical dynamic load coefficient have little effect on the range of dynamic stresses; Wheel-rail transverse dynamic load coefficient is the key factor which affects the mechanical fatigue strength behavior of the wheel web. Therefore, the wheel with a rim at the wear limit should be used to assess the fatigue strength behavior of the wheel web, and it is very important to determine the wheel-rail transverse dynamic load coefficient in order to ensure the safety of the wheel web in its whole service life.
