Numerical analysis for the normal force of magnetorheological fluids

Abstract As one of the most important mechanical parameters magnetorheological fluids (MRF), normal force has been studied by a large number researchers using various experimental equipment and methods. However, it is difficult to reveal effects particle microstructure characteristics on MRF methods, especially for such factor as size distribution. To advance this research area, numerical method calculating proposed in study. The accuracy simulation model verified with results measured plate-plate magnetorheometer. show that simulated values agree well data, which indicates feasibility methods provides new idea more intuitive comprehensive analysis MRF. Besides, data increase magnetic field intensity volume fraction will sufficiently enhance improve response time For same fraction, decline average diameter force. Moreover, increasing dispersion particles can also its
