Experimental Analysis of Magneto- Rheological Fluid (mrf) Dampers under Triangular Excitation

Magnetorheological dampers, or as they are more commonly called, MR dampers, are being developed for a wide variety of applications where controllable damping is desired. These applications include dampers for automobiles, heavy trucks, bicycles, prosthetic limbs, gun recoil systems, and possibly others. This paper first introduces MR technology through a discussion of MR fluids and then by giving a broad overview of MR dampers those are being developed. Next section includes a discussion of MR damper types, mathematical fundamentals, and an approach to magnetic circuit design. Later, MR dampers are tested for dynamic behavior under triangular excitation.
