“…[9] proposed a new model that utilizes a hyperbolic sine function to represent the hysteresis in order to describe the stiffness and damping characteristics. [10] used MRE as a semi-active vibration isolator to suppress torsional mode of vibration. Results showed that a shift of 3.9 Hz of the natural frequency and slight changes in the damping properties were observed.…”

Smart materials are materials by which their properties can be altered due to external stimuli such as temperature, pressure, and magnetic field. Magnetorheological Elastomer (MRE) is a type of smart composite material consisting of a polymer matrix embedded with ferromagnetic particles. In the presence of an external magnetic field, its mechanical properties such as stiffness change due to the interaction between the magnetic particles. Vibration isolation has been of interest to researchers for decades. In this work, simulation studies were done by utilizing different MRE models from the literature such Bignham, Bouc-Wen, Modified Bouc-Wen, Dahl and Hysteresis models on a base motion isolation (base excitation) system in order to understand the characteristics of MRE. Results showed that as the magnetic field increases, the stiffness of MRE increases significantly. Shifting in the natural frequency of the system from the transmissibility curve was observed for all models which lead to vibration isolation.

This work reported a novel magnetorheological elastomer (MRE) with different concentrations and sizes of abrasive grains, and its mechanical properties were investigated with or without magnetic field. Firstly, the MRE polishing wheel was prepared by molding with magnetic field, the microstructures of these MRE polishing wheels were observed, the magnetostrictive distribution of abrasive grains and ferromagnetic grains were discussed, and the magnetic properties was tested. Then, the magnetic hardness testing, magnetic compression experiments, and friction performance testing were conducted to investigate its mechanical properties and friction properties. Finally, a polishing experiment was designed to study the polishing performance of MRE polishing wheels. The results showed that the magnetic hardness, Young's modulus, and friction reduction of MRE polishing wheels were increased by adding abrasive grains, and the surface quality of workpiece after polishing was improved.

“…The MR effect is correlated with the weight fraction of magnetic particles in MREs. Usually the MR effect field-induced modulus was increased with the increase in the weight fraction of magnetic particles (Alias et al, 2018;Lee et al, 2018). The relative MR effect of MREs based on modified magnetic particles was increased because the chain structure of magnetic particles was arrayed more orderly in the rubber matrix (Wen et al, 2017).…”

Magnetorheological elastomers are one kind of smart materials which consist of matrix materials and magnetic particles. The mechanical properties of magnetorheological elastomers were controllable under an external magnetic field. Applications of magnetorheological elastomers are limited as a result of their poor magnetorheological effect and mechanical performance, so enhancing the magnetorheological effect of them is critical for their application. Styrene-ethylene-butylene-styrene based thermoplastic elastomer was added to natural rubber to fabricate hybrid matrix–based magnetorheological elastomers. Zero modulus of magnetorheological elastomers increased from 0.50 to 0.64 MPa and magnetorheological effect increased from 28.00% to 43.75% with the addition of styrene-ethylene-butylene-styrene based thermoplastic elastomer. The contact angle of carbonyl iron particles with the matrix showed that styrene-ethylene-butylene-styrene based thermoplastic elastomer can improve the compatibility of carbonyl iron particles with the matrix. Fourier-transform infrared spectroscopy analysis has been carried out to investigate the internal structure of hybrid matrix–based magnetorheological elastomers.
