Summary on Grant Application Form |
|
Electrorheological (ER) fluids have been the subject of detailed research investigations over many years but their widespread industrial application has always been thwarted by inadequate levels of yield stress when used in simple shear mode. During the last few years work has been directed towards assessing ER fluids in squeeze mode and this has greatly improved the prospects for their industrial exploitation since the available yield stress in this mode can be an order of magnitude greater than in simple shear. An EPSRC-funded investigation has produced strong evidence of dramatic departures from the rheological behaviour predicted by existing theoretical models and has suggested that an ER fluid in squeeze exhibits a bi-viscous characteristic but with a post-yield, non-linear, shear rate dependent shear stress. The work proposed here will continue an experimental and theoretical determination of the rheological characteristics of ER fluids in both static and dynamic squeeze and use the resulting data to design, build and test a prototype automotive ER engine mount. It is intended that commercially available ER fluids will be assessed in the engine mount under both AC and DC fields and for a range of mechanical frequencies and amplitudes.
