Comparative Study of Automotive Bumper with Different Materials for Passenger and Pedestrian Safety

Abstract

In this paper, the analysis is done on the automotive bumper to check the crashworthiness for the passenger safety. The bumper beam analyzed for the steel and composite material with the basic bumper design in the first phase, and then front part is modeled with the honeycomb and foam type in the second phase to compare the deformation and energy absorbed during the impact. A design of the automotive bumper must ensure the safety of passenger mean while, it needs to have low weight. With the role of safety, fuel efficiency and emission gas regulations are being more important in recent years that enforce the manufacturer to reduce the weight of passenger cars. In this research, a front bumper beam made of steel and composite materials to provide more energy absorption in the structural form of honeycomb and foam type is assembled at the front of the bumper and is studied for impact modeling to determine the deformation and energy-absorption behavior.
