“…The MR rheology depends on the particle shape distribution, particle concentration, additional additives, properties of the carrier fluid, temperature and the applied magnetic field [48]. Polyesters, mineral and silicone oils, synthetic hydrocarbons, polyethers, and water are common carrier liquids [40,[49][50][51][52][53][54][55][56]. In order to reduce aggregation and sedimentation, additives may be used.…”

Magnetorheological (MR) fluids are capable of manifesting a rheological behaviour change by means of a magnetic field application and can be employed in many complex systems in many technical fields. One successful example is their use in the development of dampers: magnetorheological dampers (MRDs) are widespread in vibration control systems, as well as civil engineering applications (i.e., earthquake or seismic protection), impact absorption and vibration isolation technology in industrial engineering, and advanced prosthetics in biomedical fields. In the past, many studies have been conducted on MRDs modeling and characterization, but they have usually been focused more on the theoretical models than on the experimental issues. In this work, an overview of both of them is proposed. In particular, after an introduction to the physics of the magnetorheological effect, a short review of the main mathematical models of MRDs is proposed. Finally, in the second part of this study an overview of the main issues that occur in MRDs experimental characterization is reported and discussed.

“…The rheology of MRF under the magnetic field depends, inter alia, on the shape and size distribution of magnetic particles (Foister, 1997;Ghaffari et al, 2015). In Weiss et al (2000) and Lemaire et al (1995), it has been shown that MRF containing particles of two different diameters (i.e.…”

Magnetorheological fluids (MRFs) are classified as intelligent materials whose rheological and mechanical properties can be modified by interaction with an external magnetic field. These unique features allow for a controlled change of their viscosity, which is applied in technology to build adaptive devices and effectively suppress vibrations in various mechanical systems. In this paper, we overview and discuss our previous results regarding advances and physicochemical MRF properties in the context of broader literature. We concentrated on such properties as flow, yield strength, and viscoelastic behavior under shearing flows. We briefly discussed continuum and discrete MRFs modeling. Since the magnetic core is mainly based on iron or its compounds, depending on its chemical composition, morphology, stabilizing agents, and the liquid medium’s viscosity, its rheological and micromechanical properties can be moderated. To predict the behavior of such a fluid, it is necessary to propose and implement an appropriate model. Simple models like Bingham can consider the quasi-static and dynamic behavior of the MRFs, while discrete models are applied to the development and implementation of the MRF control algorithms. Thus, analytical and numerical simulation compromise the accuracy, quantity of considered phenomena, and computational cost.

“…So far, various types of smart materials such as electrorheological fluids (ERF) (Dong et al, 2019;Liu and Choi, 2012b;Wen et al, 2008), magnetorheological fluids (MRF) (Phule, 1999;Rodrı´guez-Arco et al, 2013;Ronzova et al, 2021), ferrofluids (FFs) (Li et al, 2018(Li et al, , 2019(Li et al, , 2020Rodrı´guez-Arco et al, 2014;Usadel et al, 2019), magnetorheological gel (MRG) (An et al, 2010;Lidon et al, 2019;Pang et al, 2020), magnetorheological foam (Makarova et al, 2019;Muhazeli et al, 2021), and magnetorheological elastomer (MRE) (Bastola et al, 2020;Snarskii et al, 2021;Wen et al, 2020;Yu et al, 2015) have been identified. In some cases, the use of these materials has led to commercial-scale production by BASF (Munoz et al, 1999), Lord crop (Andrew et al, 2008), Delfi (Iyengar and Foister, 2003, 2004a, 2004b, and Ford (Ginder et al, 1996) company. MRF is an essential form of smart fluid that has been examined and investigated owing to its significant advantages over ERF and FFs.…”

Magnetorheological fluids are considered smart materials since their properties change significantly when exposed to a magnetic field, making them interesting for a variety of industries. These fluids are composed of three main components: dispersed particles, carrier fluid, and additives. The latter of which has been the subject of various studies. Therefore, this paper reviews the characteristics and parameters of the particles dispersed in additives and their impact on fluid rheological properties and stability. Also, the surface modification of magnetic and non-magnetic micro and nanoparticles have been investigated. A detailed review of previous studies has been carried out to examine the effects of various parameters such as types of coatings, coating layers, coating thickness, density change, and change in magnetic saturation, on the stability and rheological properties of MR fluids.
