Uniform Wheel Wear of a Two Axle Freight Vehicle with Friction Dampers

• Wheel reprofiling accounts for a considerable amount of the maintenance costs forfreight wagons in Sweden, and the causes can be divided mainly in three groups:wheel flats, shelling and uniform wear. In this paper the development of uniformwheel wear in a two-axle freight vehicle is studied. This wagon with Unitruckrunning gear had a major modification in the suspension elements in 2005 whichhighly reduced flange wear. The method developed at KTH for uniform wearcalculation is applied on both old and new simulation models. The influence offreight wagon specific characteristics on the wear development is also analysed, i.e.high axle load and friction damping elements.
