抄録

Particle damping is an effective method of passive vibration control. Although it has been widely used in various structural damping applications, there are some points to be examined. Few studies have focused on the difference in the effectiveness of particle dampers for systems with different natural frequencies. Also, a computational scheme for conducting large-scale simulations has not been established. The authors previously presented some computational methods for predicting largescale particle damping. The calculations are performed using equivalent large particles instead of the original-size particles. However, the range of the radius of the equivalent large particles for which these methods are effective is still incompletely understood. The objective of this study is to experimentally examine the difference in the effectiveness of particle dampers for systems with different natural frequencies and to investigate the relationship between the radius of the equivalent large particles and the validity of the computational methods.
