Influence of change in frictional condition of track rail surfaces on interaction forces in the “wheel/rail” contact

Determination of frictional condition the running surface and side top rail (lubrication) that ensures best interaction rolling stock wheels rail, reduces force action thus track stability reduced wear rails in curved tracks is relevant for all net.The objective research to determine influence surfaces on forces “wheel/rail” contact with various motion parameters (speed, radius).The theoretical experimental methods were used research. The include multioptional computer modelling axial lateral appear during freight train movement software package “Universal Mechanism”. results processed use correlation regression analysis. full-scale measurements existing processing.According results, algorithms assessment lubrication forces. option wheel has been established ensure reduction operating expenses surfacing replacement, energy costs haulage train.
