Basic Damping Property of a Double-Rod Type Damper Utilizing an Elastomer Particle Assemblage

抄録

Damping property of the damper utilizing an elastomer particle assemblage was investigated. The particle assemblage was used instead of working fluid in the damper. Basic damping property of a double-rod type damper using an elastomer particle assemblage was investigated experimentally. Forced vibration of constant frequency and constant stroke was applied to the damper. It was shown that the damping force has the hardening property of the damping force which increases with the displacement. The force depends on the stroke of vibration and the packing fraction of particles in the damper. The packing fraction of the particles increases, the force also increases.
