The main structural components were designed for a redirective and energy-absorbing crash cushion to meet Manual for Assessing Safety Hardware Test Level 3 standards.

The main structural components supported the side fender panels: the guide rails, discrete baseplates, feet, intermediate diaphragms, and an impact head. These components were designed and evaluated analytically and through numerical simulation for both lateral and longitudinal impacts to satisfy the design criteria. The guide rails were comprised of built-up sections that were welded to discrete baseplates anchored to a support pad. Intermediate diaphragms and the front impact head were frames comprised of structural steel members welded together. A nose piece was attached on the upstream face of the impact head.

Dynamic physical component testing was recommended to evaluate the capacity of the main structural components designed and accuracy of the finite element models developed. The dynamic physical component testing would be used to evaluate the system performance in longitudinal and lateral impacts.
