Abstract

The shear properties of bidisperse magnetorheological (MR) fluid have been extensively studied based on the experiment or simulation method, but the research on the enhancement mechanism is still not sufficient and need to be further investigated. In this paper, we proposed a new approach to analyze the mechanism based on the local microstructural models. The typical local configurations of particles in bidisperse MR fluid were determined by means of similarity experiment and confirmed by microstructure simulations. Subsequently, the evolution of local configurations under the shear process was simulated, and the corresponding shear resistance models were proposed. It is found that the configurations with small particles attached on sides of the chain can increase the shear resistance as well as the shear deformation, and the enhancement mechanism is determined based on the analysis of the relative position evolution of small and large particles in the local microstructures. The effect of particle size ratio on the properties of bidisperse MR fluid was also investigated. It is discovered that there is an optimal particle size ratio for MR fluid to achieve better performance.
