Based on ICSV 27paper: "Suppression of Corrugation Growth by Rail Damper", by Wilson Ho, Dominic Tse, Peter Wong, Marco Ip and Ghazaleh Soltanieh,.
Rail damper with tuned mass damping (TMD) at 550 Hz (lateral pin-pin resonance)
1/3 octave band corrugation growth data
90% suppression of corrugation growth at 500Hz
Track decay rate (TDR) improved by 3 dB/m at ~500Hz
TMD is not reflect by impulse excitation TDR measurement method
Continuous excitation TDR measurement shall be developed
