Abstract
The use of particle impact dampers for reducing railway vibration induced from moving wheel loads and the consequent noise generation is presented. The particle impact dampers for an efficient reduction of a forced vibration induced by moving loads were designed and verified using simplified models of a railway. To test the performance of the particle impact dampers, the vibration of a simplified railway attached with particle impact dampers was measured. The performance of the particle impact damper on reducing the transient vibration of a railway is investigated. 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.
