Magnetorheological (MR) fluid is a manageable fluid that exhibits drastic changes in theological properties and interchangeable depending on the applied magnetic field strength. The fluid is potentially advantageous to be employed in many applications. This paper presents the design of test equipment for the performance of compression and tension tests. Finite element method magnetics (FEMM) was used to analyze the magnetic field distribution through the MR fluid. The test equipment was constructed and modified according to the operational principles, conditions and simulation results. The tests were performed in a vertical direction to the DC magnetic field generated by a coil. Experimental results showed that the compressive/tensile stresses of MR fluids increased as the applied current increased. The test equipment was utilized to investigate the performance of the MR fluid in squeeze mode. (C) 2008 Elsevier Ltd. All rights reserved.
