Abstract
The article presents the results of theoretical studies of the interaction of the wheel set treads and rails in the horizontal plane during the movement of the electric locomotive EP2K in the curves of the rail track.
Compressive forces in the contact zone of the wheel and rail determine the crushing of the material of the contacting bodies. In the curves with radii of 350–400 m, the ridges of the the treads of the second and fifth wheel sets along the electric locomotive will contact the edge of the head of the internal rail, which determines the greatest energy consumption to overcome the forces of friction and the greatest wear of the the treads of these wheel sets. The wear value of the flange material of the rim is estimated by total volume of crushing of the rim and rail materials in the area of their contact taking into account curve radius and the length of the wheel slip path.
The obtained formulas make it possible to find values of wear of wheel flange and rail head materials depending on the ratio of their hardnesses, the radius and length of the curve and the speed of the locomotive.
