“…Focusing on the normal force of MR gels under different loading conditions, Ju et al, Mao et al, , and Xu et al , analyzed systematically the effects of particle content, actuation time of magnetic field, strain amplitude, frequency, shear rate, and temperature on the rheological properties of the MR gels and explained qualitatively the mechanical responses from the perspective of the microstructure. The temperature dependence of MR gels was also discussed. − …”

The rheological properties and shear performance of magnetorheological (MR) gels have been extensively studied based on experimental methods. However, viscoelastic theoretical models that can quantify the interaction between the matrix and particles, as well as numerical simulations on the mechanical properties and the microstructure evolution of MR gels, are still relatively few and need to be further investigated. In this paper, based on the non-Newtonian fluid equation and Kelvin viscoelastic model, a modified viscoelastic resistance model is proposed, which can describe the interaction between the matrix and particles. The consistency coefficient, flow behavior index, particle size, and motion velocity are considered comprehensively in the viscoelastic resistance equation. Based on the established theoretical model, the numerical simulation approach is developed to study the evolution of chain-like microstructures and the shear properties of MR gels. The response time of MR gels under different magnetic fields and matrixes is analyzed from the perspective of energy. It shows that the effect of magnetic field intensity on the shear strength of MR gels is consistent with the magnetization characteristics of particles. The maximum shear stress and flow stress are significantly affected by viscosity parameters of the matrix and shear rate, which are related to the strength of shear-bearing chains and recombination rate of dissociative chains. The relevant influence mechanism of the microstructures on the macroshear properties is explored.
