Abstract
Electro-rheological fluids (ERF) allow us to create «smart» devices. One of the basic
directions of application of such materials is damping in oscillating systems. This work describes
simulation model and offers the results of experimental research by rheological properties and
damping characteristic of ERF. Control signal is defined by electric field intensity, which is
changed within the bounds of 0…0.5 kV/mm. Amplitude of oscillation – up to 5 mm, oscillation
frequency is modified within the bounds of 0.5…5 Hz. The logarithmic damping decrement and
natural oscillation frequency of oscillating system, shear stress and viscosity of ERF are
determined.
