충돌 댐퍼를 이용한 레일 진동 저감 연구
Study on a reduction of railway vibration using impact dampers
- 발행 : 2014.10.29
초록
This study presents an development of impact damper and its application to reduction of railway vibration from moving roads. The impact damper for reducing trnsverse vibration from moving loads were designed and verified using simple dynamic model. To verify the performance of the impact damper, the vibration of a simplified beam with the impact damper was measured. The performance on reducing vibration for different clearance and mass ratio of the damper was investigated. The numerical solutions were verified using the experimental results from a simplified beam. The result can be utilized to reduce the rolling noise from high-speed trains.
