현 방법으로 검측된 궤도틀림 값의 원형복원에 대한 기초검토
A Basic Investigation for reconstruction profile of track irregularities measured by chord method
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 which occurs during reconstructing process and mentions the solutions briefly.
