研制了一种用于真实的基础隔震建筑的400 kN磁流变阻尼器（MR阻尼器），并通过实验测试验证了其动力特性。MR阻尼器具有950 mm（+/-475mm）冲程和旁通流量部分。为了应用于磁流变阻尼器，研制了一种新型的磁流变液。磁流变液在阻尼器中具有颗粒沉降的特性。作者研制了一种新的磁流变液，它能充分地保持磁流变液中的颗粒，以满足磁流变阻尼器的正常使用。本文对分析模型进行了讨论。并将宾汉粘塑性模型计算结果与试验结果进行了比较。结果发现，该分析模型是有用的预测磁流变阻尼器的能力。
A 400kN magnetorheological damper (MR damper) for a real base-isolated building was developed and its dynamic characteristics were verified by experimental tests. The MR damper has 950mm (+/-475mm) stroke and by-pass flow potion. A new type of Magneorheological fluid is also developed in order to apply to the MR damper. MR fluid had a property of the settlement of particles in dampers. Authors developed a new MR fluid, which keeps the particles in the fluid adequately enough for usual use of MR damper. Analytical model was discussed in this paper. The force by the bingham visco-plastic model was compared with the results of experimental tests. It was found that this analytical model is useful to predict the capacity of the MR damper.
