磁流变阻尼器是利用磁流变效应产生可控阻尼力的一种智能机械装置，通过调节磁流变液的屈服应力来控制阻尼器的机械性能。文中设计了一种基于剪切模式与挤压模式相结合的磁流变阻尼器。并通过有限元分析模拟了磁流变阻尼器电磁线圈产生的磁场。用3种不同条件下静态载荷分别对阻尼器进行实验，这3种载荷分别是剪切模式、挤压模式、剪切模式和挤压模式相结合。该实验结果表明，基于混合工作模式下的磁流变阻尼器电磁学性能通常情况下高于单一模式的磁流变阻尼器。

Magnetorheological (MR) damper is a semi-active suspension device that uses MR fluid to produce controllable damper. The mechanical properties of the suspension can be controlled by adjusting the yield stress of MR fluid. This paper presents the design of a new concept for MR damper with a combination of shear and squeeze working modes. Finite element method is utilized to simulate the magnetic field generated in MR damper. The experimental tests are performed under quasi-static loading in three different conditions , namely shear mode , squeeze mode and combination of both modes. The results show that the mixed mode MR damper has produced a unique damping characteristic where in general , a higher damping force has obtained in mixed mode than single mode.
