... in determining the operational reliability of the wheel/rail system. Because of wheel wear, wheel re-profiling is usually required for proper wheel-rail interaction. However, wheel re-profiling reduces the wheel radius and increase flange thickness. Therefore, the strain energy density in the wheel tread...

... 2022 by ASME and The United States Government that the distribution of oil and water influences the contact pressure and adhesion coefficient. On the other side, several researchers have experimentally evaluated the effect of water and oil contaminations on the wheel-rail interaction. Several methods...

... lateral curving forces. The curving forces resulting from a positive AOA (corresponding to a left-hand curve) are less than those for negative AOAs, mainly due to the force offset due to the wheel taper.

... that the surface finish continues to change beyond the time that the traction forces reach their plateau, and its effect remains far more gradual than NTBL. Keywords: Surface Finish, Natural Third Body Layer, Wheel-Rail Interaction, Surface Roughness, Friction, VT-FRA Roller Rig INTRODUCTION The wheel-rail surface...

... Interaction, VT-FRA Roller Rig INTRODUCTION The wheel-rail interaction, which results in generating creep forces, occurs over a small area known as contact patch. The wheel surface condition [1], the third body layer accumulation [2], and the pressure distribution are highly dependent on the size...
