Basic operating principle of the Magneto-rheological fluid clutch was stated. A Magneto-rheological fluid clutch used to control the fan speed of engine cooling system was designed based on the electromagnetic finite element analysis. The magnetic lines of force and the magnetic flux density distribution were analyzed. And the influence of material and structure forms of the clutch shell on the magnetic flux density was studied. Research results show that the material of clutch shell has significant effect on the distribution of magnetic flux density and air gap in the clutch shell has great effect on the magnetic flux density in MRF working area, which are expected to provide references for the design of similar products.
