Abstract

Measured decay rates(DR) [1] provide an estimation for track dynamic properties along rails. To entirely estimate the vibration propagation behaviors of tracks for Beijing metro, DR measurements of different track structure forms are carried out. Including standard track with DTVI2 fasteners un/installed with rail dampers, Egg fastening system track un/installed with rail dampers, and ladder track. All the test results are compared with the suggested lower limits of TSI-NOI [2] and shown as: (1) Installing with rail dampers can improve the DR characteristics for tracks in some frequency bands; (2) Some bad wheel/rail contact may be induced by the deficiencies of DR characteristics at some frequencies of tracks; (3) Comparing with lower limits of TSI-NOI may conduct the optimization of track structure.
