Abstract
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.
