Abstract EN
Magnetorheological fluid is a new type of smart material that is sensitive to magnetic fields and has controllable performance.
It is widely regarded for its unique magnetorheological effect and good rheological properties.
For materials, the microstructure determines its macroscopic properties.
In order to better study its macroscopic properties, it is necessary to have a more comprehensive understanding and deep understanding of its microstructure.
In this paper, the magnetization process of magnetorheological fluid is analyzed from a microscopic point of view.
Based on Newton’s second law, the dynamic model of particle motion is established.
The magnetic force, repulsive force, and viscous resistance of magnetic particles are analyzed.
The finite difference numerical calculation method is used.
The velocity-Verlet algorithm simulates the static microstructure chaining process of the magnetorheological fluid and the dynamic chaining process under shear force under different influencing factors.
At the same time, a static observation device and a shear observation device were developed to observe the microstructure chaining morphology of magnetorheological fluid under different influencing factors, and to study the dynamic chaining law of magnetorheological fluid under the action of a shear force.
Therefore, a reasonable contrast index is established, and the numerical simulation results are compared with the experimental observation results.
