Damping Characterization of Friction Energy Dissipation for Particle Systems Based on Powder Mechanics and Experimental Verification
We established a friction energy dissipation model for particle damping based on powder mechanics. We investigated the influence of geometric features of the damper on damping characteristics; and the geometric feature studied was the depth and length of the rectangular particle container. The work...

We established a friction energy dissipation model for particle damping based on powder mechanics. We investigated the influence of geometric features of the damper on damping characteristics; and the geometric feature studied was the depth and length of the rectangular particle container. The work done by the frictional force between the particle layer and the effect of particle filling rate on the vibration damping characteristics was also explored. We analyzed the friction energy dissipation model, and the relationship between the particle filling rate and the vibration damping. The experimental results show good agreement with the friction energy dissipation model, which verifies the proposed simulation prediction. The results have shown that the particle damping technology can greatly consume the structure kinetic energy, and the vibration reduction effect of particle damping depends mainly on the interaction of the particles near the top. A proper filling rate of particle systems can result in an optimal effect on vibration reduction, which will provide the engineering applications with the theoretical guidance and design criteria.
