Investigation and Simulation on Magnetic Hysteresis Properties of Magnetorheological Fluid

Magnetorheological fluid (MRF) materials are used in many devices as smart materials. However, the application of this material is limited to damper or vibration absorber because of the lack of understanding of its magnetic hysteresis properties. This paper systematically presents our recent investigation and simulation on the magnetic hysteresis properties of MRF materials. The measurement of its magnetic hysteresis property was accomplished by using a two-dimensional single sheet tester with an MRF sample container. An extended large-scale atomic/molecular massive parallel simulator, which is combined with the Stoner-Wohlfarth hysteresis model, was employed for simulating the magnetic hysteresis properties of MRF material. The measurement and simulation results are compared, analyzed, and discussed. The results will be useful for modeling of magnetic hysteresis properties of MRF materials.
