Study on the formation mechanism of rail corrugation on curved track

Many researches on the problem of corrugation formatting on the track of railway have been reported in the world. But most of those researches are carried out by phenomena analyzing which occurred on real track or by just using theoretical model and scaled model simulation. For the reason of technical difficulties, theoretical researches proved by practical experiment are very rare. By using the corrugation formatting model considering with the characteristic of creep between wheel and rail interface we successfully fixed the formation mechanism of corrugation. Theoretical analyzing results agree well with the phenomena measured on stand experiment and on commercial line.
