Background/Objectives: The purpose of the project is to formulate MR fluid and fabricate MR damper.MR damper is modelled to provide semi-active suspension system in vehicles. Methods/Statistical analysis: The stiffness of suspension system can be varied by using MR fluid. The project aims at fabrication of MR damper and preparation of magneto-rheological fluid, which can vary its viscosity inside the damper in the presence of magnetic field. MR fluid varies its stiffness under the magnetic field; this principle is used to control the damping action of the shock absorber. Findings: The iron particles in the MR fluid opposes the carrier fluid passing through piston head holes. This resistance builds strong opposition for shock absorber oscillation. As With increasing the current provided the number of cycles the damper can sustain is rising which can result in more lifetime of damper. Improvements/Applications: This Technology can be further implemented in Brake System. These MR Dampers are used in certain automobile industries and vehicles. Some automobile industries are working on it to implement in the near future.
