콘크리트 궤도의 최적 탄성에 관한 연구 = A Study on the Optimum Stiffness of Concrete Slab Track

다국어 초록 (Multilingual Abstract)

In recent railway construction, the concrete slab track is getting highlighted as main stream in track type. However, it is the fact that there are different opinions in selection of the optimized spring coefficient of elastic pad. In this study, the performance of vibration reduction in different stiffness of rail pad for ballasted track was compared, and the changes in characteristics, such as static/dynamic deflection of components, vibration acceleration, insertion loss etc., were analysed by using ISI Program for various types of rail fastening system used in concrete slab track.
It was concluded that the fastening system with softer pads has shown the better performance of vibration reduction in concrete slab track and the optimized static stiffness has been calculated to 21.1kN/㎜ for conventional railways, 17.6kN/㎜ for high-speed railways and 17.8kN/㎜ for subways.
