Abstract

Smart materials can sense changes in the surrounding environment and are able to generate a desired response that is based on these changes. Magneto rheological (MR) fluids are non-colloidal suspensions of micrometer sized magnetizable particles suspended in non magnetic liquids. In this study a new damper working on squeeze flow mode is developed. The damper is tested with three types of MR fluids and studied for damping coefficient. It is found that damping coefficient increases with increase of current up to 2 ampere and beyond that there will be no appreciable improvement due to magnetic saturation. The performances of these MR fluids were compared.
