Abstract

ABSTRACT
Electro-and magneto-rheological fluids are smart, synthetic fluids changing their
viscosity from liquid to semi-solid state within milliseconds if a sufficient strong
electric or magnetic field is applied. When used in suitable devices, they offer the
innovative potential of very fast; adaptively interface between mechanical devices
and electronic control units. This paper gives an overview on the basic properties of
electro and magneto-rheological fluids and discusses various phenomenological
models for rheological fluid dampers in vibratory systems. The dynamic response of
a quarter-car model with MR- suspension damper is introduced and compared with
one uses a conventional viscous damper.
