SEVERE WEAR OF ROLLING/SLIDING CONTACTS

The wear of wheel flanges against the sides of rails is shown to be caused by rolling/sliding contacts sustaining high cyclic stresses at low slide/roll ratios, when these conditions are reproduced in the laboratory severe metallic wear is initiated when the resultant shear stress, which is dependent on both normal (pressure) & tangential (friction) forces, exceeds a critical value. The results are discussed in terms of K.L. Johnson's (1962) shakedown limit and the material's stress/strain characteristics. It is concluded that the severe wear of contacts at low slide/roll ratios is caused by high resolved cyclic stress that result in continual plastic deformation of the surface layers.
