Investigation of the Track Irregularities Reconstruction Methods

초록

In Korea mid chord offset method has been used to measure the track irregularities. This method has been also used all over the world widely because of its accessibility and the operational excellence for measured data. But it has been pointed out recently that track irregularities reconstructed from measured data have unexpected noise in the high frequency area as the defect of this way. This study shows the cause of noise that occurs during reconstructing process and mentions the solutions briefly.
