摘要：

Rail corrugations involve different resonances of track and vehicle systems. Due to the severe and abnormal rail corrugations in Beijing newly opened metro line(especially in some sections with anti-vibration measures), and in order to identify the main reasons of these, according to the investigation information, three dynamic FE Models of track structures commonly used in metro lines, are established. From vibration frequency response function point of view, the effects of track structure forms and their parameters to the rail vibration and the formation of rail corrugation arc analyzed. By calculation, frequency oriented vibration characteristics and its relationship with the rail corrugations of different types of track structures are displayed by considering different relative parameters, such as stiffness under rail and sleeper spacing. The suggestions for further study are proposed.
