In a wide range of engineering applications of ER fluid, shock absorbers employing ER fluids, whose damping force can be controlled continuously and promptly through electric signals, is one of the most prospective applications of ER fluid. In this paper, the theoretical midel and method to predict the damping force of ERF shock absorbers are established.展开更多
