The general objective of the whole-Body Response (WBR) research program was to generate data on the kinematics and response of human surrogates in a realistic automobile impact environment. The program used a test configuration consisting of an idealized hard seat representation of a car seat with a three-point harness restraint system. Three different severity levels of crash test conditions were used. The human surrogates tested in this program were fifteen male cadavers * , a Hybrid II (Part 572) Anthropomorphic Test Device and a Hybrid III ATD recently developed by General Motors. In addition, mathematical simulations of the response and kinematics of a 50th percentile male occupant were performed at the three levels of crash severity, using the MVMA Two-Dimensional Crash Victim Simulator. The primary utility of the data generated by this program is for comparing the similarities and differences in response and kinematics of the various types of human surrogates and in pointing out areas that need improvement in both anthropomorphic test devices and mathematical models.
