THE LIMITS AND POSSIBILITIES OF TEST-RIG EXPERIMENTS IN THE DEVELOPMENT OF NEW WHEELSET TECHNOLOGIES WITH REGARD TO MATERIALS

Wear and frictional behavior of pairs of materials is influenced by the properties of surfaces and the surface materials. Transfer of experimental results to practical situations is dependent upon the different states of the surface. It is possible to simulate the motions of real vehicles with the use of "corrected" elastic constants which take into account the range of different states of deformation of wheel treads and rails. A statistically sound determination of surface layer states in real wheel/rail systems and in test rigs must be established. Experiments carried out at Munchen-Freimann's WP II test rig are determining friction/creed curves with different surface states to insure proper elastic constants for actual conditions.
