Research on the Influence of Track Structural Parameters on Abnormal Rail Corrugation

Abstract:

To solve the abnormal rail corrugation problem of Beijing Metro Line 4, the track structural parameters comparative tests were carry out in the Metro Line 1,2 and 4. Metro Lines 1 and 2 were chosen based of the Beijing Subway Survey and previous successful experiments. The comparative analysis was based off of rail static geometry, dynamic displacement and the lateral acceleration. The test results proved the stiffness of line4 is weaker than line1,2 and suggestions on steps to prevent and correct the metro rails abnormal corrugation will be formulated.
