An experimental study by Stanway and his colleagues (1992) demonstrated the feasibility of employing electro-rheological (ER) fluids in squeeze for controlling mechanical vibrations. This study showed how, by incorporating an ER squeeze-flow cell into a vibration isolator supporting a 60 kg mass, magnification of the input displacement at resonance could be reduced by a factor of six. It was also shown how, by a simple switching operation, the arrangement could provide the high-frequency isolation properties associated with a lightly-damped system. In this paper the authors discuss the development of mathematical models to characterize the dynamic behavior of electro-rheological fluids operating in the squeeze-flow mode. A theoretical approach is summarized and an experimental facility, designed to validate the models is described. Aspects of control are also discussed.
