This paper proposes a new parametric dynamic model for magnetorheological (MR)
fluid dampers. The proposed model adapts the regularized Bingham model to
accurately reproduce the hysteretic behavior of such dampers. The optimized model
parameters are then obtained by making the model predictions as close as possible to
the reported experimental measurements. As one application of the model, the
performances of MR dampers in mitigating free and forced cable vibrations
are numerically investigated and evaluated. Numerical simulations results
demonstrate the accuracy and the effectiveness of the proposed dynamic hysteretic
regularized Bingham model (HRB) in comparison with a standard Bingham
model.
