Evaluation of wear reduction measures for wheelsets and rails operated in high mountain conditions

Abstract

There are about 20 major factors influencing wear of railway system of a wheel, but the most critical include service and lubricant of rails. On the basis of locomotive depot Rodakovo the analysis of regularity of wear of a surface of wheels of the locomotive during the long period of time has been made and the method of correction of wheels has been offered and calculations which have shown that during operation of wheel couples there can be several corrections of a profile of a wheel before full grinding that leads to increase in life cycle of a wheel have been carried out. Also the approximate method for assessment of efficiency of introduction of methods of maintenance and repair of a wheel which includes the cost of life cycle of a wheel of the locomotive which will be developed further has been offered, estimating at the same time several methods, comparing their efficiency and choosing the most preferable options in the set parameters.
