초록

The use of impact dampers for reducing railway vibration induced from moving wheel loads and consequent noise generation is presented. The impact dampers for efficient reduction of impact vibration induced by moving loads were designed and verified using simple dynamic models. To test the performance of the impact dampers, the vibration of a simplified beam attached with various impact dampers was measured. The performance of the impact damper on reducing the transient vibration of railway is investigated. The effects of clearance and mass ratio on vibration reduction was analyzed. The numerical solutions using finite element method were verified using the experimental results to find the vibration reduction mechanism. The result was utilized to reduce rolling noise radiation from moving trains.
