  • Damping Force Properties of Air Inflow Type Particles Damper

抄録

<p>In this study, influence that the damping force properties of the damper using particle assemblage received from flow rate of the inflow air were investigated experimentally. Zirconia balls of 0.5 mm in diameter were prepared as the particle. The damper was installed in the horizontal direction. The air was poured into the damper from bottom side holes, and the air was poured into outside from upper side holes of the damper. The forced displacement of the sine wave was given to the damper. The damping forces and displacements of the damper were measured. When the flow rate of the air is low, the damping force of the damper decreased as the flow rate is increased. On the other hand, when the flow rate of the air is high, the damping force of the damper increased as the flow rate is increased.</p>
