Bumper System Mass Reduction through Hybrid Material and Process Strategy 2006-01-1661
With the increased focus on fuel economy in the automotive industry today vehicle mass reduction is becoming increasingly important to automotive engineers. A common method to reduce mass for bumper reinforcement beams is to use aluminum extrusion technology. However, the use of aluminum extrusions comes at a higher cost than comparable steel systems. Two hybrid design approaches for bumper reinforcement beams are presented in order to reduce mass while maintaining a lower cost than aluminum bumper systems.
