Resumo(s)
his paper provides a brief description of
MR fluid technology and MR fluid based
devices. Analytical and experi
mental investigations about MR dampers covering their rheo-
logical properties and hysteretic behavior will be
carried out. In the first section an overview
of the basic properties of the MR fluids and the fluid behavior under different flow regimes
are presented. Then, a selection of numerical models to simulate MR dampers behavior will
be presented based on the available literature.
To obtain and analyze the hysteretic behavior
of a MR damper, a commercial device was expe
rimentally tested under several input excita-
tions. Based on the experimental results an identification procedure was carried out to deter-
mine the necessary parameters to develop a numerical model. Finally, results from
experimental investigations and numerical
analyses are summarized and compared.
