Abstract

This study developed a new neck injury risk function suitable for use in frontal crashes with occupant orientation ranging from predominantly horizontal to predominantly vertical in the occupant anterior-posterior (A/P) direction. In this study, 36 cadaveric head/neck complexes and 6 whole cadavers were tested under impact scenarios with varying total head mounted mass and center of gravity locations. Matched Hybrid III and THOR dummy tests were also performed. The resulting injury criterion is based on a beam model of the lower cervical spine and is expressed in mathematical form. The calculated values were comparable to single axis injury tolerance valuesdescribed in the literature and in existing motor vehicle injury standards for the upper cervical spine (FMVSS-208, 2003). Beam criterion values (BC) of 1.0 correspond to a 50% risk of an AIS 2 injury in the human cervical spine. The THOR dummy was found to reproduce the kinematics of the cadaver better than did the Hybrid III dummy. However, response curves showed differences between the THOR and the cadaver that were due to anatomy. Forthe covering abstract see ITRD E141569.
