This paper deals with the idea of implementing the magneto Rheological bumper in the front overhang of the four wheeler, which reduces the loss and deformation of vehicle during accident. It includes the basic characters and properties of the magneto rheological fluids (MR) and implementation of MR damper in bumpers of four wheelers. Research results of the past decades in Magneto Rheological fluids and their applications are reviewed. The whole paper includes MR fluids as active component in Impact reducing system. It is one of the important materials used by major engineers in designing components like brakes, dampers, clutches. Here Magneto rheological techniques are used to reduce the impacts which are occurred during collision of vehicles. Here the vibration is arrested by controlling the intensity of Magnetic field. Vibration produced during impact is partially absorbed by the magnetic field and remaining by spring action. This paper discusses about the conventional bumpers and replacing it with magneto rheological bumpers which we called as Impact Reducing System. It also deals with fabrication and assembly of Magneto Rheological Dampers in bumpers.
