“…A similar observation is seen for all the other modes but is not shown here for brevity. Hence, it can be concluded from Figure 19(c) that the damping performance is better at higher particle densities for all the bending modes, which agrees with the reported literature (Panossian, 1991;Xu et al, 2004a,c;Hu et al, 2007) and indicates that the energy dissipation increases with increases in particle density. This has been validated in both predictions from RBF network and experimental investigation.…”

“…The DEM technique was used by many researchers to carry out studies of particle dampers (Saluena et al, 1999;Friend and Kinra, 2000;Chen et al, 2001;Mao et al, 2003Mao et al, , 2004. A DEM was used to model particle damping by accounting for the effects of particle size, friction between two particles, and number of particles (Hu et al, 2007). It has been observed that the damping performance depends on mass ratio and material density.…”

“…The vibration energy of the main structure is dissipated by collisions between particles and container wall and between particles. It has been widely investigated and used in the aviation and mechanic area, but relevant research in civil engineering is just in the early stage and is only limited in the earthquake‐induced vibration control area . Research and engineering practice show that the damping performance of particle damper under seismic load is favorable.…”

“…Particle dampers are passive control systems that absorb the incoming energy through impact of particles with each other and with the walls of the container resulting in exchange of momentum between the particles and the primary system. Such devices have been used for years to reduce the vibrations of machines and structures [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Papalou et al [14][15][16][17] reported that a properly designed particle damper replacing one of the top drums of a classical multi-drum column without capital can achieve substantial reduction of the motion.…”
