Damping Properties of a Damper Using an Elastomer Particle Assemblage Containing Fine Particles

摘要

Damping property of a damper utilizing a particle assemblage, which is the damper using a group of particles instead of oil in an oil damper, was investigated experimentally, when the particles were elastomer particles containing micrometer-size spherical particles. Silicone particles were prepared as the micrometer-size spherical particles dispersed in the elastomer particle. It was shown that the basic damping force characteristics of the damper using elastomer particles containing fine particles is basically the same as that of the damper using pure elastomer particles. The maximum damping force of the damper becomes large by dispersing micrometer-size particles in the elastomer particle. When the total volume fraction of fine particles in the elastomer particle is constant, the maximum damping force of the damper using smaller fine particles becomes stronger.
