  • Change of Damping Properties of Particles Damper by Air Inflow

抄録

<p>In this study, influence that the damping force properties of the particles damper received from inflow of the air were investigated experimentally. Zirconia balls of 0.5 mm in diameter were prepared as the particles. Damping forces were measured under constant piston speed conditions by the load cell. The damping forces increased as the displacement is increased. The gradient of the damping force changed to three phases. In the all phases, the damping forces decreased as the air weight flow is increased. On the other hand, under constant air weight flow conditions, the damping forces did not change with displacement speed.</p>
