Modeling Damping Force for a Translational Damper Based on Shear-Thinning Giant Electrorheological Fluid

Abstract

The mathematical model of electrorheological fluid damper which is based on the flow mode has been proposed in many articles. In this paper, a new optimization model of the giant electrorheological fluid damper, which is based on the shear thinning mathematical model, is proposed and simulated numerically with Matlab. The mathematical model of giant electrorheological fluid damper without considering the shear thinning model is also simulated numerically in this paper. The data of the damping force-excitation displacement of the damper are tested by the 810 Material Test System. By comparing the simulated data with the experimental data, it can be seen that the model considering the shear thinning mode can predict the damping force that the damper can produce.
