Design and Analysis of Bumper Beam and Energy Absorbers by Using Composite Materials

Abstract At present the production of automobile is in increasing rate especially India which is one of the largest producer and consumer of automobile. India uses wide variety of automobile like bus, car, van, truck and heavy vehicles. But India have a poor road quality and the driving facilities are less which results in severe road accident. This results in severe collisions of vehicles and it cause damage to both vehicle and passengers. Bumper is one of the key factor which helps in avoiding damage to vehicle and passengers present inside the vehicle. Thus all vehicles will have bumper for safety purpose. The bumpers are made of different type of materials to ensure safety of the passengers and to reduce the weight of the vehicle. The production of bumper in composite material results in increased safety during collision and it is cheaper and reduces the weight of vehicle. The cross-section of beam, energy absorber and its materials is designed and analyzed, with referring to the result safe and strong bumper system is discussed. When compared to current bumper, the composite bumper with energy absorber results in greater shock absorption and increased strength which increase the overall effectiveness of the bumper and its function.
