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.
