Abstract

A tapered octagonal frame rail tip for use with automotive bumpers is configured to axially crush in a controlled manner in the event of a vehicle impact. The rail tip is tuned to carry a constant load while crushing to absorb a higher amount of energy than alternative crush modes. Body mounts for attaching front end sheet metal or other body components to the frame rail tip are configured to centrally align loading to avoid interference with the desired axial crush.
