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.

Two-point wheel - rail contact investigation

Golubenko A., Kostyukevich A., Tsyganovskiy I, Nozhenko V.

Transport Problems

2011

T. 6, z. 3

115-122

This paper describes a wheel - rail contact for a case when one contact point is located on the wheel tread while the other is on the wheel flange. The locations of these points are determined for both wheels for given lateral displacement and yaw angle of a wheelset. Numerical simulation results are presented for new and worn rail-wheel profiles in order to demonstrate a developed algorithm.

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

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

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.
