IMPROVING RESOURCE PERFORMANCE BY METRO RAIL WARNING GRINDING
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 167, Issue 1
Abstract
In this work the influence of preventive grinding rails and lubrication treated surfaces on rails underground resource that is determined by the intensity of contact-fatigue defects origin side of the working surface rail head curve plots lines underground. On the basis of studies of the influence of parameters grinding and lubricating the contacting surfaces of the model of contact "wheel-rail" on the development of defects contact-fatigue origin and experimental research in service of rail ways Kharkiv subway developed methods of measuring resource outer rails of the rail curves thread subway tracks sites. Comparison of the current version of the resource exploitation and external curves metro rail routes to the proposed sites, which include the performance of grinding contact surfaces and grease. Due to this defect is made forecasting the development of contact fatigue life and the origin of experimental plots underground ways to determine a rational frequency of preventive grinding rails.
