In order to develop an MR Damper, two new shaped magnetorheological (MR) valves are proposed : straight path type and zigzag path type. Utilizing a magnetic field analyzing software (JMAG-Studio), the magnetic field inside of the valve channel is analyzed on the conditions of various applied electric energies and channel materials that have different magnetic permeability. The estimated pressure drop properties of the MR fluid flowing through these two new shaped valves were evaluated, based on the calculated magnetic field strengths and the measured rheological properties of the MR fluid in flow mode. The calculated pressure drops were obtained for different magnetic permeability of materials, applied electric energy and flow rate, and compared with measured results. A suitable MR valve for MR damper is discussed and proposed.
