摘　　要：磁流变离合器是通过磁流变液的剪切应力进行传递转矩的器件。对多盘式磁流变离合器进行磁路的设计,首先应用磁路欧姆定律,结合考虑不产生磁路磁饱和效应,初步确定磁路结构参数并采用有限元分析的方法对磁路进行仿真,对不同磁导率的磁轭材料进行分析。仿真结果表明绝大多数磁感线都通过多盘式离合器的磁流变液工作面,并且在相同条件下,相对磁导率较高的磁轭材料可以提高工作间隙的磁感应强度。A magneto rheological （MR） clutch is a device to transmit torque by the shear stress of MR fluids. Magnetic circuit of multi-plate magneto-rheological fluids （MRF） clutch is firstly designed, and both the magnetic circuit Ohm＇s law and the rule of avoiding magnetic saturation were applied in the calculation of struetural parameter. And with emulation of magnetic circuit by finite-element analysis, which is followed by the analysis of magnet yoke materials with different magnetic permeability. The results of emulation show that most of magnetic induction lines pass through the warking face of magneto- rheological fluids. Magnet yoke materials with high relative permeability can improve the magnetic induction in working gap under the same conditions.
