Regularities of shaping of a wheel profile as a result of deterioration of the rolling surface in exploitation

In the middle of the 90s the deterioration of wheels flanges and lateral rail surfaces on roads in the countries of CIS from natural process of wear process of surfaces has turned to the sharp problem which has received the status of a Ťrail plagueť. On separate roads the lateral deterioration of rails has reached 1 mm times 10 tons, by exceeding a level of normative deterioration in some times. Thus the run of wheel pairs between regrinding on flange undercuts was reduced in by 3-5 times [5]. In the article some ways of elimination of deterioration of wheels and rails are considered. The technique of process modeling of parameters changes of deterioration is offered.
