In this paper, the effect of temperature on rheological properties of magnetorheological (MR) gel is investigated under rotational steady shear and oscillatory dynamic shear. A kind of fluid-like MR gel (MRG) was firstly synthesized by mixing carbonyl iron powder (CIP) with polymer matrix. Then, the relationship between yield stress, normal stress of MRG and shear rate under six temperatures and four magnetic field strengths were studied by rotational shear experiments. The results demonstrate that the dependence of shear stress on temperature displays an opposite tendency in comparison with that of normal stress on temperature. Moreover, maximum yield stress, one of the most important parameter of MR materials, decreases with the increment of temperature. Under oscillatory dynamic shear test, storage and loss moduli and normal stress of MRG all increase with temperature when a magnetic field is applied, which presents a contrary trend in the absence of a magnetic field. Related mechanisms about the alternation of microstructures of MRG were proposed to explain the above-mentioned phenomena. This paper is helpful in fabricating semi-active engineering devices using MR materials as a medium.

The thickening mill equipment installed on the second floor is damage for the structural and personal health. In this study, the vibration conditions of thickening mill equipment and its vibration isolating based on MR damper technology are investigated experimentally and simulacrum. First, the vibration test of thickening mill equipment installed on rigid foundations is operated, and the results show that while the rigid foundation can suppress equipment vibration, it also deteriorates vibration transmission to the ground, which results in vibration displacement of the ground exceeds the permissible range by 120%. Second, a MR damper utilized to form the elastic foundation is tested to acquire the force–velocity characteristics, which is described by the proposed Bingham model. The comparison results between the model predicted and measurement data delicate that can effectively describe the correlation between the dynamic properties of MR damper and the coil current/excitation conditions. Finally, an elastic foundation consisting of eight coil springs and several MR dampers is proposed to replace the rigid foundation of the thickening mill equipment. Together with the ON–OFF skyhook control algorithm, the properties of the elastic foundation to reduce the force transmission rates are tested based on the simulation model. The simulation results suggest that the designed elastic foundation can effectively reduce the vibration transmission from the thickening mill equipment to the ground, which can decrease the peak force transmission rate by 95.5%. This study provides a guide to technological transformation methodology of the thickening mill equipment to reduce structural vibration.

Owing to some of its specific advantages, magnetorheological fluid (MRF) has drawn significant attention in a broad range of modern precision machining fields. With the diversification and increase in demand, many novel structural configurations and processing methods have been applied to mechanical machining equipment. Although different applications using MRF have been proposed in the existing literature, the classification, latest approaches, and further trend are not understood clearly for the machining field. Therefore, the current applications such as machining auxiliary equipment and surface polishing equipment that used MRF are summarized from 2016 to 2020, in this article. Especially, some detailed structures of equipment are investigated, and relative limitations are analyzed based on the characteristics of MRF. Finally, in view of the current equipment, advantages and defects are briefly reported; the developing trends of modern precision machining with MRF are discussed. Therefore, in the state-of-the-art review, the significant role of MRF in the machining field is emphasized, which paves the way to innovative development and market selection.
