针对磁流变传动散热问题，设计了一种新型的磁流变流体传动装置，并对该装置的转矩进行了分析。基于电磁学理论，设计了该装置的磁路。采用有限元法对测量装置的磁场进行了模拟。结果表明，当电流为1.6 A时，工作磁感应强度可达0.5 T，满足设计要求。工作空间内的磁感应强度随着磁导材料的激励电流和磁导率的增大而增大；随工作空间大小的增加而减小；并随着磁环尺寸的增大而增大。工作区内磁感应强度由强到弱依次为DT4C、20钢、45钢。实验结果与仿真结果一致。
Aiming to solve the problem of magnetorheological transmission heat dissipation, a novel magnetorheological fluid transmission device is designed, and the torque of the device is analyzed. Based on electromagnetic theory, the magnetic circuit of the device is designed. The finite element method is used to simulate the magnetic field of the measurement device. Results show that the working magnetic induction can reach 0.5 T when the current is 1.6 A, which can meet design requirements. The magnetic induction intensity in the working space increases with the increase of the excitation current and permeability of the magnetic conductive material; decreases with the increase of the size of the working space; and increases with the increase of the size of the magnetic ring. The magnetic induction intensity in the working area is DT4C, 20 steel, and 45 steel from strong to weak. The experimental results are consistent with the simulation.
