Summary:This paper presents the results of an experimental and analytical study of the performance of particle impact dampers using a cylindrical container. This damping is a form of impact damping in which particles collides with the cylindrical surface of the container. The dynamics of the damper is solved by Discrete Element Method (DEM). The validity of the numerical method is examined by comparison with experimental results. The effect of some of the major system parameters such as the mass ratio, container dimensions and particle radius on the structural damping is studied.
