Abstract

Electro-rheological fluids are capable of providing continuously variable damping forces in response to an electrical stimulus. Many prototype ER dampers have been described in the literature, most of these based upon exploiting the variable shear properties of the fluid. It is only recently that an alternative mode of operation--squeeze flow--has been identified and investigated. Squeeze-flow offers the prospect of simple forms of construction coupled with the ability to provide force levels consistent with industrial specifications. In this paper the authors summarize the principles of squeeze-flow operation and introduce a quasi-steady model to account for the vibrational behavior of a squeeze-flow cell. An experimental facility is described in detail and test results are compared with theoretical predictions. The paper concludes with some thoughts on future work into squeeze-flow behavior.
