Property Tests and Mathematical Model for Magneto-Rheological Fluid

Abstract:

The magnetic particles coated with the carbon are used in the magneto-rheological fluids (MRFs) and the coat-like structure slow down the sedimentation of MRFs. Meanwhile, after the performance tests, the new MRF has the low viscosity and good ability of the recovery. These characters have more advantages in the application fields. Based on the prepared MRF, a shearing model that considers the interaction force between the adjacent chains was presented. By applying the proposed model, some conclusions are reached. The volume ratio of the magnetic particles has an important effect on the yield stress of the MRFs. The shear strain where the maximum shear stress happened has something to do with the volume ratio of the magnetic particles.
