Abstract

Object: To show the lack of wheelset operating life efficiency use in case traditional methods of wheel tread reprofiling were used in the process of repair works. To consider the possibilities of further improvement of this process on the basis of new reprofiling technologies, using the deep and high-speed grinding. Methods: The methods of wheel tread reprofiling were analyzed, the effective process solutions, based on theoretical conclusions and current practical knowledge, were studied. Results: Wheel set wastage in case of using the traditional ways of reprofiling was estimated. Preliminary parameters of wheelset reprofiling modes using high-speed grinding were estimated, providing for the increase in wheel set operational life and reprofiling performance enhancement. Practical importance: The appropriateness of rolling stock wheel tread reprofiling, by using the method of infeed high-speed profile grinding, was presented. The obtained results may be applied in the development of requirements specification for wheel tread reprofiling machine at repair facilities of the Russian Railways.
