Abstract

A double-gap magnetorheological (MR) cell is designed, constructed, and validated using finite element method magnetostatics simulations, computational fluid dynamics calculations, and experimental data with Newtonian fluids and conventional MR fluids for a range of particle concentrations and external magnetic field strengths. This new cell is a generalization of the twin-gap device. It is capable of reaching very large magnetic field strengths and shear rates, avoiding normal force overload. More importantly, it is optimized for magnetic field homogeneity.
