Reducing the wheel-rail system wear intensity with thermomechanical impact

Abstract

The article discusses the method of controlling friction in the wheel-rail system, which suggests using compressed air that passes through the Ranque-Hilsch tube and is supplied to a wheel-rail contact area as a third body. This method allows to provide efficient energy and resource saving, stabilize the amount of locomotive traction and braking effort required for effective starting and braking of rolling stock, reduce wear intensity in the wheel-rail system and increase the level of environmental safety of the railway transportation process.
