Characterization of a commercial magnetorheological brake/damper in oscillatory motion

摘要

A Bouc-Wen element has been employed by a number of researchers to model magnetorheological (MR) linear dampers with success. In this work, a modified commercial MR brake was modeled using a Bouc-Wen element and experimental data gathered on the torque response of the brake to oscillation. An optimization was undertaken using torque and displacement time-series data to determine the parameters of the brake model, and comparisons were made between experimental and predicted torque response.
