Information × Registration Number 0216U009010, 0116U005320 , R & D reports Title The influence of parameters of grinding rails on the development of dominant metro rail defects popup.stage_title Head Voronin Sergiy Volodimirovich, Доктор технічних наук Registration Date 08-09-2016 Organization Ukrainian State University of Railway Transport popup.description2 The report presents an analysis of the technical condition of the Kharkov subway rails leading to the determination of their defects. choice of subject was justified by sections of track on which there is a rapid development of defects in drawing 11. The proposed theoretical basis of rational calculation of the roughness of the surface of the rail in the area of ??development defects in drawing 11 in a variety of contact conditions, namely the dry contact and contact with the lubricant. These theoretical studies on the rational surface roughness of the side rail heads in curved sections of underground track. Provided laboratory investigation of the influence on the roughness of the rail surface friction and wear in contact with the wheel. The program and the method of testing the selected path areas to establish the influence of the parameters of the finish grinding rails on the pace of development of major defects in the subway. Past performance tests and reflects the results of studies of the effect finish grinding the rails on the rate of defects of underground test sites path. It was developed a method of forecasting resource rails with different parameters finish grinding and practical recommendations on the content of the rails in the curved sections of the path CE "Kharkiv Metropoliten".
