Dual Hysteresis Model of MR Dampers [PDF]
Frontiers in Materials, 2020 This study concerns the modeling of the hysteretic behavior of magnetorheological (MR) dampers. In general, hysteresis is one of key factors influencing the output of such actuators. So far, more attention has been paid to studying the combined hysteretic behavior of MR actuators by observing the relationships between the output (force/torque) and the ...

Reduction of vibrations in blanking by MR dampers [PDF]
CIRP Annals, 2010 The break through shock during sheet metal blanking operations generates uncontrolled high reverse loads, mechanical vibrations and loud noise that may cause problems such as fatigue cracks in the press components, premature wear in tooling and great discomfort for press operators.

MR Damper Modeling Performance Comparison Including Hysteresis and Damper Optimization [PDF]
IEEE Access, 2021 This research paper represents the analysis and simulation of semi-active suspension using non-linear modeling of the Magneto-Rheological (MR) suspension with consideration of the hysteresis behavior for a quarter car model. The research is based on the assumption that each wheel experiences the same disturbance excitation. Hysteresis is analyzed using

APPLICATION OF MR DAMPERS TO VARIABLE DAMPERS
Doboku Gakkai Ronbunshu, 2004 ダンパーの減衰力を任意に変化させることができれば, 橋梁の地震応答を抑える上で有利であり, 構造物の応答に応じて特性を変化させることのできるバリアブルダンパーの利用が効果的であると考えられている. 本研究では, 電流で減衰力を制御可能なMRダンパーを用いたバリアブルダンパーの有効性を実験, 解析の両面から検討する. 小型MRダンパーの特性を明らかにすることを目的として繰り返し載荷実験を行った後, 模型橋の振動台加振実験を行い, 地震時のMRダンパー及び橋梁の挙動を調べた. また, バリアブルダンパーをモデル化し, 橋の地震応答を地震応答解析によってよく再現できることを示した.

Temperature Sensitive Controller Performance of MR Dampers [PDF]
Journal of Intelligent Material Systems and Structures, 2008 Magnetorheological (MR) dampers can experience large temperature changes as a result of heating caused by energy dissipation, but control systems are often designed without consideration of this fact. Furthermore, due to the highly nonlinear behavior of MR dampers, many control strategies have been proposed and it is difficult to determine which is the

Passive damping of cables with MR dampers [PDF]
Materials and Structures, 2005 This paper describes the measured damping characteristics of a cable with perpendicularly attached magnetorheological fluid damper. First, the damping of the free cable is measured for reference. Then, the magnetorheological fluid damper is connected to the cable in order to measure the resulting damping at different constant damper current levels. The

Experimental Study on Modified MR Damper
Journal of Physics: Conference Series, 2021 Abstract Many systems in Industrial sector face the problems of vibrations. Vibration control equipment like MR damper is employed to minimize these vibrations. In this context, magenetorheological fluid (MR Fluid) is introduced as a damper fluid to improve the damper’s vibration reduction capacity significantly.
