ImageThe Bumper Project is managed by a membership consisting of North American steel producers, bumper manufacturers, and representatives of the OEMs. The Project addresses technological challenges, such as the development of a system that is capable of absorbing energy, and the development of lightweight steel facebar systems for light truck vehicles.

The importance of bumper design has grown significantly in recent years due to increased safety standards, the need to decrease vehicle weight, and the introduction of new high-strength and ultra high-strength steels. In addition, the work of the Project Team has grown in importance due to the increased interest in alternative materials such as aluminum and composites.

 



Technical Deliverables
Great Designs in Steel 2007: Hot Stamped Bumper Design - Challenges in Development for Meeting Multi-Regional Requirements
Steel bumper PowerPoint presentation from the March 2007 Great Designs in Steel seminar.
Steel Bumper Systems for Passenger Cars and Light Trucks - Revision 3: Full Report (4.7MB)
A recently updated Bumper Design Manual guides automotive engineers through the latest in materials and manufacturing innovations.
Current Trends in Bumper Design for Pedestrian Impact
Worldwide, the pace of development in pedestrian countermeasures is increasing rapidly. To better understand the state of the art in bumper design for pedestrian impact, a survey of literature and patents has been performed. Two general approaches to reducing the severity of pedestrian lower limb impacts were identified: (a) Provide cushioning and support of the lower limb with a bumper and a new lower stiffener, or (b) Use the bumper as a platform for impact sensors and exterior airbags. This study focused on the first approach. Excluding bumper sensors, airbags, and nondesign-related articles, a total of 130 relevant technical articles and 147 patents were identified.
