플로팅 슬래브궤도용 방진재의 성능에 관한 연구

초록

The paper presents an application of the model to a practical problem of train-induced vibrations. The aim of this study is to vertify for performance of isolators which was developed in KRRI supported floating slab track. Laboratory tests on developed isolations show that the energy dissipation, under cyclic loading of constant amplitude, can be suitably represented by a combination of a viscous and a hysteretic damping. Also, other tests for structural performance are carried out, such as elastic material test, compression test and so on. The specimen, 400×400×300㎜, is placed between two stiff steel plates designed to uniformly distribute the compression stress on the surface.
