Abstract
The invention relates to a compact device which serves as a controlled rotary damper using smart fluids and which can be easily adapted to different applications. The device consists of a rotor having perforated curved blades joined to the solid or hollow rotary shaft which moves inside a casing filled with smart fluid. External magnetic or electric excitation is applied to the device in order to apply a magnetic or electric field to the smart fluid and, in this way, provide a controlled resistance for damping.
