VIBRATION CONTROL USING MAGNETORHEOLOGICAL DAMPERS

Abstract

Magnetorheological (MR) dampers have emerged as highly effective semi-active vibration control devices capable of real-time adaptation to dynamic loads across structural, automotive, aerospace, and machinery applications. These devices leverage the unique properties of magnetorheological fluids (MR fluids), whose rheological behavior changes rapidly under magnetic fields, enabling variable damping forces with low energy consumption and fast response times. This article comprehensively examines the fundamental principles of MR damper operation, reviews state-of-the-art research in design, modeling, control strategies, and experimental validation, and presents a methodology for evaluating vibration mitigation performance. Key results from comparative analyses of control algorithms demonstrate the effectiveness of MR dampers relative to passive and active systems. Implications for future research directions in materials, intelligent control, and industrial implementation are discussed.
