Nhtsa’s Thor-nt Database

This paper provides a comprehensive overview of the many tests involving the THOR-NT advanced frontal impact dummy that are contained within the NHTSA test database. Since its release in 2005, NHTSA has collected data from over one hundred tests involving the THOR-NT. These include sled tests, vehicle tests, and component tests at different speeds and configurations. This paper serves as a reference for describing the various test series, which include those aimed at assessing biofidelity, evaluating instrumentation, and establishing qualification and injury criteria. This paper also provides analytical examples that demonstrate the utility of the database in studying dummy-related issues. New auxiliary tools, such as data processing software and computer models, are also described. Finally, this paper summarizes some of the lessons learned from this broad test experience, and documents actions that are being taken to enhance dummy performance and acceptance by the international community.
