磁流变（MR）流体制动器是一种通过磁流变流体的剪切力传递扭矩的装置。MR旋转制动器具有其制动扭矩响应于外部磁场强度而快速变化的特性。本文从理论上研究了圆柱形磁流变液制动器的设计方法。推导了磁流变液在制动器内传递扭矩的方程，为制动器的筒形设计提供了理论依据。在此基础上，经过数学处理，计算出了圆柱形磁流变液制动器中环形磁流变液的体积、厚度和宽度。
A magneto-rheological (MR) fluid brake is a device to transmit torque by the shear force of an MR fluid. An MR rotary brake has the property that its braking torque changes quickly in response to an external magnetic field strength. In this paper, the design method of the cylindrical MR fluid brake is investigated theoretically. The equation of the torque transmitted by the MR fluid within the brake is derived to provide the theoretical foundation in the cylindrical design of the brake. Based on this equation, after mathematical manipulation, the calculations of the volume, thickness and width of the annular MR fluid within the cylindrical MR fluids brake are yielded.
