Abstract
Aiming to prepare high-property magnetorheological fluids (MRFs), experiment materials, optimized preparation processes, experimental methods, experimental procedures and test methods were elaborated for high-performance MRFs. Two carrier fluids, novel additives and three antiwear agents were selected to prepare MRFs. The characteristics of the MRFs samples including the settlement stability, zero-field viscosity, shear yield stress and wear resistance were tested and analyzed. The measurement of shear yield stress was obtained using a self-designed MRFs characteristics testing test-bed. The microstructure of unworn and worn magnetic-particles were observed using scanning electron microscope. Experimental results showed that HFGEL-310 and SD-104 mixed in a certain proportion can enhance settlement stability of MRFs, three antiwear agents can slow down the wear of MRFs to a certain extent and MRFs-31 with AlN had the best anti-wear performance. MRFs based on PAO10 with HFGEL-310 2.7%, SD-104 2.9% and AlN 5% was high-performance MRFs with good overall properties.
