磁流变液阻尼器在土木工程和结构工程中得到了广泛的应用。作者设计了容量为60kN的被动型阻尼器，该阻尼器由常规磁流变液和永磁体组成。利用牛顿流体力学和宾汉流体力学对流体流动阻力产生的阻尼力的设计方法进行了估算。特别是参照Buckingham-Reiner方程，推导出Bingham流体模型的设计公式。通过施加正弦输入位移和改变孔板直径来考察其动态特性。测量了速度-力关系和耗散能量-频率关系。将解析法得到的阻尼力与实验结果进行了比较。作者证实，这两种方法的分析结果与实验结果吻合较好。
Magneto-Rheological Fluid (MRF) damper has been studied for application to civil and structural engineering. Authors have designed the passive type damper of capacity 60kN which consists of a conventional MRF and permanent magnet. Design methods of damping force generated by fluid flow resistance are estimated by using Newtonian fluid and Bingham fluid mechanics. In particular, design formula about Bingham fluid model is extracted by reference of Buckingham-Reiner equation. Dynamic properties are examined by applying sinusoidal input displacement and by changing orifice diameter. Velocity-force relations and dissipation energy-frequency relations are measured. Damping forces obtained from analytical view and experimental results are compared. And authors have confirmed that both are in good agreement between the analytical view and experimental results.
