In this paper, an effective numerical method for the damping performance of an impact damper with granular materials is proposed. In this method, the effect of granularity on the dynamics of the impact damper with granular materials can be considered by using Discrete Element Method (DEM). It is shown that the damping performance of impact damper with granular materials depends on the following parameters: mass ratio, number of particles and clearance. The validity of this numerical method is examined by comparison with the experimental results.
