Friction interaction management in two-point "wheel-rail" tribocontact

Kostyukevich A., Gorbunov N., Nozhenko V., Kovtanets M., Tsyganovskiy I.

Transport Problems

2012

T. 7, z. 3

53-59

The results of studies on the possibility of application of ozonized air to reduce the wear and tear in the tribocontact "wheel-rail" are presented. The technique of influence estimation of ozonized air, as activator surface, on the friction interaction in wheel-rail contact, is proposed, the results of experimental research results are presented.

Adhesion control in the system of "wheel-rail"

Gorbunov N., Kovtanets M., Prosvirova O., Garkushin E.

Transport Problems

2012

T. 7, z. 3

The paper reviewed the proposed promising method for jet-abrasive treatment of contact surfaces of wheel and rail. The mathematical model of metal removal and the depth of penetration of abrasive particles, which are used in the method for determining surface roughness profile formed by jet-abrasive processing. Concluded that the choice of parameters and treatment regimes for optimal profile of the surface roughness.

The effect of the electrification of sand on the interaction of friction in tribological contact

Gorbunov N., Kostyukevich A., Kravchenko K., Kovtanets M.

Transport Problems

2011

T. 6, z. 4

In the article questions of the effectiveness of the presence of abrasive granular material in contact “wheel-rail” in the implementation of the optimal traction and its quantity on the surface of the rail. A method for determining the charge abrasive particles.Experimentally proved the effectiveness of electrification of sand before applying it to tribocontact to improve traction.
