초록

도심지에 건설되는 철도역사, 선로구조물 등 철도시설물의 경우 소음 및 진동 저감 설계의 중요성이 더욱 커지고 있다. 특히 선하역사는 구조물 위에 선로가 놓이게 되므로 철도 진동과 이로 인한 2차 소음을 효과적으로 차단할 수 있는 진동 제어 대책이 더욱 필요한 상황이다. 수직형 방진장치는 열차 운행으로 인한 진동이 직접적으로 전달되는 선하역사 등 철도시설물의 진동 저감에 효과적으로 적용될 수 있으나, 수평형 장치에 비하여 개발이 미진한 상황이다. 이 논문에서는 열차에 의한 진동을 효과적으로 저감하기 위해 개발 중인 마찰쐐기형 방진장치를 소개하고, 동적성능 검증을 위한 시험 결과를 제시하였다. 개발된 방진장치의 성능 검증을 위하여 시제품을 적용한 콘크리트구조물에 대한 강제 가진시험을 수행하였으며, 시험결과를 통해 방진장치의 방진성능 및 동특성을 검증하고 방진장치 개선사항을 검토하였다.

In the case of railway facilities in cities such as a railway station or a bridge, the significance of design for reducing vibration and noise is getting more significant. The vibration control solution is in need especially for an elevated railway station to block vibration of a train and secondary noise effectively. Even though a vertical vibration isolation device is able to be applied effectively to railway facilities such as elevated railway stations which transfer vibration directly from a train to a structure, the development of the vertical device is much slower than a horizontal vibration isolation device. In this paper, a vibration isolation device using wedge type friction material which is currently developing to reduce train-induced vibration effectively is introduced and test results for verification of dynamic performance is also presented. The vibration test on a concrete structure equipped with the developed vibration isolation device is conducted through which the isolation performance and dynamic properties are verified and needs for improving the performance of the device is identified.
