Temperature fields of components in relative sliding motion of the wheel-rail system can be analysed on the quasistationary approach

In the work the regularities of the influence of the chemical composition of steels for railway wheels on their mechanical properties by means of complex physical and chemical composition criteria. Based on the results of laboratory experiments and of ana... see more

Formulation of the problem. The achievement of high mechanical properties of the railway wheel rim made from carbon steel is ensured by the highly dispersed perlite structure formation in it and a small amount of pre-eutectoid ferrite, which is allocated ... see more

Cleavage formation is a process nucleation caused by  the high internal stress produced followed by joint deformation on the surface and cycles change of temperature in railway wheels after braking using brake shoes. 

The observed questions of estimate degree decrease density dislocations in carbon steel rail wheel after electrical impulse treatment.

 In the article the information on calculated forces of interaction in the system "wheel-rail" is presented at movement on curve sections of a track with a speed less than 160 km/h and the change of wear of wheels is predicted.

The observed questions of estimate influence content of carbon in steel on the formation defects on the surface rail wheels at exploitation. 

This article offers the methods of calculation of the start points of contact during wheel set-rails family interaction. The states of wheel set are investigated; the types of possible specific wheel set states, turning-over of rolling stock elements and ... see more

In the article the research results of occurring defects in railroad wheels, the systematization and attempt of explaining the causes of occurring them are presented.
