Abstract
In order to use shear yield stress model of magnetorheological fluid more accurately, the influence of particle size, particle spacing and magnetic field intensity on the model error of single-chain dipole is compared and analyzed based on the finite element model. The results show that particle size and particle spacing have few effects on the single-chain dipole model, but the magnetic field intensity is the most important factor affecting the error of single-chain dipole model. As the magnetic field strengthens, the error of the single-chain dipole model decreases gradually. Based on the research, the single-chain dipole model is optimized by finite element method. Experimental results show that the error of optimized single-chain dipole model is reduced by 80% compared with that of the model before optimization, which is more accurate.
