4.4.7 Performance Comparison Between Particle Dampers and Multi-unit Impact Dampers

Multi-unit-single-particle dampers have been introduced in the previous sections. The main feature is that there is no collision between particles. For a two-degree-of-freedom system, the particle mass is divided into two parts, one in the x direction and the other in the y direction, so as to reduce the system response caused by the two directions excitation, as shown in Fig. 4.27.
