Abstract
The particle damping is found to be remarkably strong for a broadband range. Moreover, the shear friction is determined to be the major contributing mechanism of damping, especially at a high volumetric packing ratio. The numerical and experimental findings suggest that the best damping effect might be achieved by using a design of multiple particle chambers involving an appropriate combination of the impact, friction and shear mechanisms, in contrast to a transverse-type particle or single-mass damper.
