Abstract
Magneto-rheological fluids (MRF) and electro-rheological fluids (ERF) are smart, synthetic fluids, changing
their viscosity from liquid to semi-solid state, if a magnetic or an electric field is applied. This paper treats the
rheological properties of fluids and discusses various phenomenological models for rheological fluid devices.
MRF and ERF have attracted considerable interest due to their wide range of use in vibration dampers for
semi-active vehicle suspension systems, machinery mounts or seismic protection of structures; their damping
capabilities can be very quickly adjusted by applying a variable magnetic or electric field. The advantages and
disadvantages concerning the using in applications of MRF and ERF are presented in [2], [4].
