Development and Testing of MR Damper

Abstract

Conventionally systems are designed to resist the causes of vibrations through a combination of strength, deformability, and energy absorption. Use of Magnetorheological fluids in vibration absorbing dampers is one of the methods available for smart damping now days. The essential characteristic of MR fluids is their ability to reversibly change from free-flowing, linear viscous liquids to semi-solids having controllable yield strength in milliseconds when exposed to a magnetic field. Theoretical analysis was carried out for MR Damper, resulting equations are solved in MATLAB. Analytical model and experimental analysis results are compared.
