Abstract

Bumper system of a vehicle absorbs the kinetic energy of full-frontal and offset collision. The bumper of a vehicle is the most prominent component considering the safety of the occupant. Design of new bumper system should be done in a way in which the deceleration of the occupant and intrusion in the passenger compartment must reduce. A new way to improve safety in the frontal collision is the implementation of the hydraulic damper in the bumper system of the vehicle. Magnetorheological (MR) fluid damper is suitable for absorbing high-speed impact energy. Implementation of MR damper in the bumper system will reduce the occupant injury. A dynamic model of a vehicle has been developed. This model has four degrees of freedom and damping provided by an airbag is also taken into account, thus giving a more accurate prediction of response during the collision. A new configuration of MR damper has also been proposed.
