The Function of Bumper The Function of Bumper AbsorberAbsorber

Bumpers typically extend widthwise across the front and rear of a vehicle and are mounted to rails that extend in a lengthwise direction. Energy absorbing bumper systems attempt to reduce vehicle damage as a result of a collision by managing impact energy and intrusion while not exceeding a rail load limit of the vehicle. The efficiency of an energy absorber is defined as the amount of energy absorbed over distance. A high efficiency energy absorber absorbs more energy over a shorter distance than a low energy absorber. High efficiency is achieved by building load quickly to just under the rail load limit and maintaining that load constant until the impact energy has been dissipated.

Increasing the stiffness of an energy absorber generally increases the efficiency of the absorber since a stiff energy absorber builds load more quickly than a less stiff absorber. In addition, there generally is less intrusion with a stiff energy absorber than with a

less stiff energy absorber.
