Abstract
In this paper, vibration response and acoustic radiation of a thin-walled box with particle dampers are predicted. First, the effects of the collisions and friction between the granular inter-particles are interpreted as an equivalent nonlinear viscous damping based on multiphase flow theory of gas-particle. Then the contribution of particle damper is estimated as an equivalent mass-damper system. Next, the model for the thin-walled box with particle dampers is implemented in the finite element method using COMSOL Multiphysics Software. Finally, the vibration response and acoustic radiation of a thin-walled box with particle dampers based on multiphase flow theory are predicted using such original and novel simulation method. An experimental verification is conducted and a good agreement is obtained between the theoretical results and the experimental data.
