FSAE Impact Attenuator

Impact Attenuator An impact attenuator is a structure used to “decelerate impacting vehicles gradually to a stop” 1. By gradually decelerating the racecar, the frame and driver are protected from significant deformation and injury. The bulk of impact energy is transferred into the deformation of the impact attenuator structure.
