中文摘要：

为有效隔离汽车发动机的振动，提出一种基于挤压模式的磁流变悬置的结构与工作原理。并对磁流变悬置的磁路进行了理论计算。针对磁路的轴对称特性，采用Matlab／PDEtoot建立磁路二维有限元仿真模型，并进行静态磁场仿真分析，确定磁路的主要结构参数。基于磁流变液Bingham模型和流体动力学理论，建立磁流变悬置力学模型。对磁流变悬置进行动态特性试验，并与理论计算值进行对比分析。结果表明试验值与计算值基本吻合，所提出的基于挤压模式的磁流变悬置设计方法是可行的。

英文摘要：

To effectively isolate the vibration of automobile engine, the structure and working principle of an engine magnetorheological （MR） mount based on squeeze mode is developed, and magnetic circuit of MR mount is calculated according to the structure of MR mount and electromagnetic theory. Based on the axisymmetric characteristics of magnetic circuit, a magnetic circuit two-dimensional finite element simulation model is established with the MATLAB/PDEtool software, and the main structural parameters of magnetic circuit are determined according to the simulation analysis of static magnetic field. The mechanical model of MR mount is established according to magnetorheological fluid （MRF） Bingham model and hydrodynamic theory. The dynamic characteristics test of MR mount is carried out and the testing results are compared with the calculated results. The results show that they agree well, and the proposed design of MR mount based on squeeze mode is proved to be right.
