도상에 따른 진동특성에 관한 연구

In this study, the vibration according to type of trackbed was relatively compared by 3-dimensional finite element analysis using ABAQUS and deduce effective trackbed about vibration reduction. Commonly used trackbeds, asphalt, ballast and concrete, were applied to the track structure. The train speed was 300km/h. According to the result current study, ballast was most effective material for the vibration reduction.
