It responses rapidly in the presence of an applied electric field. This phenomenon has potential applications in industries and technology. In the present paper, ER fluids and its mechanical characteristics are discussed. Using a simple damping model, the response analysis of a vibration system with ER dampers has been carried out. A numerical example is given to demonstrate the application of the present theory. The results show that ER dampers can significantly reduce the vibration amplitude of the system.
