Abstract
This paper presents the results of an experimental and analytical study of the performance of particle dampers using some cavities. This damping is a form of impact damping in which particles collides with the cylindrical surface of the cavities. 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 cavity number, container dimensions and mass ratio on the damping studied.
