Dampers are crucial for controlling the vibration of dynamic systems. A cost-effective and unconventional device of increasing damping is a particle damper. In this study, damper torque characteristics of a rotary elastomer particle damper using spherical and ellipsoidal elastomer particles are analyzed. A prototype of a rotary elastomer particle damper is produced and experimentally tested. Numerical simulation was performed to understand the behavior of spherical elastomer particles, while visualization experiment was conducted to observe the behavior of ellipsoidal elastomer particles. It was observed that the increase of packing fraction and rotor speed increases the damper torque. The spherical particles are capable of producing higher damper torque compared to ellipsoidal particles. Increase of aspect ratio of ellipsoidal particles decreases the damper torque.
