The performance of an impact damper with granular materials in horizontally and vertically vibrating systems is investigated both experimentally and analytically. The motion of the damper is solved by the discrete element method, which is often used in investigations of soil mechanics and powder technology. This method makes it possible to consider the effect of granularity on the damping performance. In this method, the dynamics of the entire system is determined by analysis of the motion of the individual particles. The validity of this numerical method is examined by comparison with the experimental results. The difference in the damping effect in horizontally and vertically vibrating systems is considered.
