Features of mathematical modeling of dynamic processes of car passing railroad turnouts

Abstract: Dimensions and tolerances in the “wheelset — railway track” system are interconnected, since the normative values of geometric parameters and shape of the elements of the wheelsets and the track's upper structure are directly de pendent. In 2018– 2019 in order to establish the minimum permissible thickness of wheel flanges for freight cars in operation and to determine the influence of the thickness and shape of wheel flanges on the safe passage of turnout elements, JSC “VNIIZhT” conducted comprehensiv… Show more

“…-the most prospective problem solving to reduce the intensity of wheel comb wear of rolling stock and rails is the use of the systems of lubrication, rational algorithms for lubrication and SL which correspond to operation requirements and have a high index of the ability to increase the resistance of friction surfaces to transition to catastrophic modes of wear (Ud, %) [5].…”
