DISCUSSION ON THE STRENGTH OF WHEEL-AXLE FOR HIGH SPEED TRAIN AND SOME FUTURE PROBLEMS

When the train speed increases to more than 200 km/h, the variance and increase of wheel-load will be more remarkable than in present cars. The train speed must be increased carefully, the bogie construction, the track construction and its maintenance method must be fully investigated. In future, problems of the thermal crack, tire flat and residual stress are very important for wheel-tire and the fatigue strength under complex stress amplitude and the study of increasing press-fit parts strength are very important for axles. According to all data, the critical speed of wheel-tire will be 300 km/h.
