This paper presents an optimised design of a high-efficiency magnetorheological (MR) valve using finite element analysis. The MR valve is composed of a core, a wound coil, and a cylinder-shaped flux return. The core and flux return form the annulus through which the MR fluid flows. The effects of magnetic field formation mechanism and MR effect formation mechanism on the MR valve performance are investigated. Analytical results of the magnetic flux density in the valve indicate that the saturation in the magnetic flux may be in the core, the flux return, or the valve length. To prevent the saturation as well as to minimise the valve weight, the dimensions of the valve are optimally determined using finite element analysis. In addition, this analysis is coupled with the typical Bingham plastic analysis to predict the MR valve performance.
