Particles are solids. However, they have fluidity. Therefore, we can replace the fluid of a oil damper with the particles. The damping force of this damper is produced by friction and collision of the particles. The damper does not use a fluid, so its structure is simple and durability is good. A number of factors have an effect on damping force of the damper. In this research, the damping force of the damper using glass beads is investigated experimentally under constant vibration conditions. It is shown that the damping force and absorption energy of the damper are affected by size and packing fraction of the particles, and frequency of vibration.
