Experimental study of a multi-electrode cylindrical ER fluid damper for in-plane motions

摘要

Abstract: Electro-rheological fluid (ERF) shock absorbers are semi- active vibration control devices that utilize ERF to control the damping capacity of the dampers. The focus of this work is on the experimental study of a multi-electrode, cylindrical ERF damper designed for in-plane motion. Several three- electrode ERF dampers are built and tested specifically for vibration damping of in-plane motions. The force-velocity loops were obtained and examined for different voltage levels and electrode lengths. !35
