| Summary: | This paper presents a comprehensive review of magnetorheological (MR) fluid
technology in valve mode or flow mode application. Special emphasises are put on the three major
elements in MR valve applications namely the MR materials, rheological behaviour and the device
design. In the duration of past ten years, the MR fluid materials and valve mode devices evolved
from conceptual design to functional applications. Spiralling efforts is going on around the world
contributes to this huge steps of development. The accomplishment of this technology is
contributed by the good design of the valve mode device as well as the refined properties of MR
fluid. Good MR fluid measured through its stability in sedimentation behaviour, the large ratio of
‘on’ and ‘off’ state viscosity and maximum effects of shear stress under induction of magnetic
field. This paper first presents the material composition of MR fluid components for valve mode
application. Then, the rheological behaviour of MR fluid in valve mode environment is discussed.
Finally, this paper reviews the development of MR valve design and their applications in past ten
years. |
