| Abstract: | The effects of thermal loading on wheels from heavy haul freight car braking is discussed.The(research) efforts having been made in this aspect is reviewed briefly.Also,computer simulation stress and temperature results are presented for several typical thermal loading cases,including drag and stop braking scenarios.The case of a handbrake left on a moving wheel are presented,and the effects of brake shoe tread position on temperature results are examined.Wheel removals and failures related to thermal loading are also discussed. |
