NUMERICAL ANALYSIS ON THE RHEOLOGICAL CHARACTERIZATION AND FINISHING EFFICIENCY OF MRAFF PROCESS
RÉSUMÉ
Magnetorheological fluid consisting of nano-magnetic particles, featured by advantages, such as, short reaction time, good controllability, high stability, high shear stress and so forth, involves the advanced intelligent material. The said fluid can lead to a solid–liquid phase change under magnetic field, and thus change Newtonian fluid to non-Newtonian fluid, wherein the solid resembling mechanical property can be used to devise practical engineering parts different from traditional counterparts. Magnetorheological abrasive flow finishing (MRAFF) process is one of the technologies applying magnetorheological fluid to precision processing. However, because the mechanism, coupled with magnetic field, thermal flow field, and multiphase flow, is complicated, it is difficult to obtain parameters.
This research develops the numerical means to analyze the characteristics of magnetorheological fluids and the finishing efficiency of abrasives, and meanwhile, investigates the cutting efficiency on curved-surface parts and the variations in magnetorheological fluids using the characteristic equations of magnetorheological fluid under different mesh numbers, inlet pressures, and magnetic field intensities.
