Abstract

A combined theoretical and experimental study of electrorheological (ER) fluid dampers is presented here. A moving electrode ER damper was built and tested for its dynamic characteristics for different electric field strengths and varying displacement amplitudes. Based upon the phenomenology observed in the experimental results, an augmented nonlinear model is proposed to describe the dynamic characteristics of the damper. The six model parameters are estimated from the experimental hysteresis data. The force versus displacement and force versus velocity hysteresis cycles are then reconstructed using these estimated parameters. The results show that the model captures the nonlinear damper behavior quite accurately. The importance of the various components in the model is illustrated.
