In this paper, a kind of magnetorheological fluid, containing nano‐Fe3O4, was prepared in order to study the influence of nano‐Fe3O4 content on its normal force characteristics. Firstly, the microscopic force model is constructed and the microscopic static analysis is carried out. Secondly, the force of the magnetic chain under impacted is simulated by using the numerical simulation method of ANSYS finite element analysis and a plate‐to‐plate shear test system is established. The results show that the normal force of the magnetic chain is enhanced by the supporting force of the nano iron powder embedded in the magnetic chain. At the same magnetic induction intensity, the normal force of the magnetorheological fluid gradually increases with the increase of the mass fraction of nano‐particles. When the mass fraction of the nanoparticles is 7 %, the normal force reaches the maximum. [ABSTRACT FROM AUTHOR] |
