Effects of Container Size, Stroke and Frequency on Damping Properties of a Damper Using a Steel Particle Assemblage

抄録

A damper using a particle assemblage is a damper using particles instead of a working oil in a standard oil damper.Two kinds of container size for double-rod type damper using a steel particle assemblage were prepared. Effects of container size of the damper, stroke and frequency of forced vibration on the damping force were investigated experimentally. The damping force of the damper depends on both the frequency of forced vibration and the length of the container of the damper, however, basic property of the damping force is almost independent of the stroke of forced vibration.
