Abstract
The development of controllable suspension dampers for ground vehicles is the subject of much current research. In this paper the authors describe aspects of a design methodology for controllable dampers which use electro-rheological (ER) fluid as the working medium. This methodology is based upon a non- dimensional characterization of ER fluid data which allows measurements obtained from small-scale tests to be used to predict the behavior of industrial-scale vibration dampers. The ER damper is represented via a Bingham plastic constitutive relationship, augmented by terms to account for fluid inertia and compressibility. An industrial-scale test facility is described and the first available set of experimental results are presented. A comparison is made between model predictions and observed behavior.
