비접촉식 레이저진동계를 이용한 매립형궤도 및 일반 자갈궤도의 변위계측 및 분석

It is important to measure and monitor the displacement of rail in real-time under vehicle loadings and to analyze the changes in long-time. In this study, relative behaviors are to be analyzed for the embedded rail along with conventional ballast rail track in the site. Please note that the embedded rail system is certified as Transportation New Technology #13 in 2013 and was applied in 2009 for the first time in Korea. To measure the vertical displacement of rail track under the vehicle, the non-contact, laser vibrometer was used in a distance to secure the field safety. As a result, the developed embedded rail system proved to have excellent durability and reliability for abnormal track displacement including the vertical displacement.
