摘　　要：介绍了磁流变技术的基本原理,阐述了磁流变液的组成成分、工作模式、比较常见的动力模型。通过磁流变液的动力学参数测试试验,得到了不同条件下的储能模量和损耗模量;结合流变学理论公式对试验结果进行数据拟合,得到了不同电流下,磁流变液产生的附加刚度、附加阻尼与振动频率之间的关系式。This paper introduces the basic principle of magnetorheological technology,describes the composition of magnetorheological fluid,working mode and common dynamic model.The energy storage modulus and loss modulus are obtained by testing the dynamic parameters of the magnetorheological fluid.Based on the theoretical formula of rheology,the relationship between additional stiffness,additional damping and vibration frequency of the magnetic rheological fluid is obtained.
