The damping effect of an impact damper with granular materials in a vertically vibrating system is studied both experimentally and analytically. The motion of the damper is solved by Discrete Element Method (DEM), which is often used in the investigation of soil mechanics and powder technology. Mechanical elements like springs, dashpots and frictional sliders are used to express the contact force. It is shown that the performance depends on the particle radius and the damper geometry as well as various physical parameters. The validity of the numerical method is examined by comparison with experimental results.
