Abstract: Based on the formation theory of rail corrugations caused by slip-stick vibrations of wheel- sets, an emphatic analysis and summary are made of the influencing factors of corrugations from the aspects of track conditions, bogie structures, contact performances between rail and wheel, and operation conditions. Nine kinds of retarding measures for corrugations are suggested. Some of these measures are tested in field tests, and good results are achieved. Thereby the correctness of the formation theory of rail corrugations and the effectiveness of the retarding measures proposed in this paper are validated to some extent.
