ANALYSIS OF THE CONTACT SURFACES FOR T81 AND PRSF 2018 RIM PROFILES WITH RAIL PROFILES USED IN THE URBAN RAILWAY OF THE CITY OF SOFIA

Vladimir Zhekov

The report examines the contact surfaces in the interaction of rim and rail profiles used in the urban railway in the city of Sofia. The contact of T81 track profiles and new PRSf 2018 profile with 49E1 rail, 60R2 and 60R1 channel rails and B60 stemless rail are considered. The gap during normal contact interaction of a rim and rail profile was investigated. An analysis of the two rim profiles in terms of their contact with the rail profiles is made and recommendations for optimization are presented.
