  1. 1. Magneto rheological fluid damper.(MR damper) Project: 1 Presented by: Supervisor: Dr.Riaz Muhammad Kifayat ullah
  2. 2. CONTENTS Aim & Objective Introduction Proposed Methodology Current status of Project Gantt Chart Project Deliverable Conclusion Reference 2
  3. 3. Introduction A magneto rheological damper or magneto rheological shock absorber is a damper filled with magneto rheological fluid, which is controlled by a magnetic field, usually using an electromagnet. This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet. 3

  5. 5. Aim & Objective The aim of the project is to fabricate an MR- damper which can absorb maximum vibration or shock. 5
  6. 6. Features of MR-Damper Absorbs more vibration. Simple hardware. Requires low power. Controllable damping. Easy to control Have higher magnitude of yield stress 6
