Abstract
In this paper, a numerical modeling method for particle damping is presented. The numerical modeling is executed by using analytical results for the motion of the granular materials in the damper cavity under sinusoidal excitation. The damping effect for particle damping is modeled as equivalent additional mass, nonlinear spring force and viscous damping force by means of the discrete element method. The validity of the method is examined by a comparison of the experimental results. Analytical solutions are provided to estimate the response of the primary system under sinusoidal excitation.
