Comparison of Whole Body Response in Oblique and Full Frontal Sled Tests
Efforts to improve restraint design for occupant protection require a detailed knowledge of human kinematic response and thoracic deformation. This study presents the spinal displacement response, thoracic deformation and restraint forces of five male post‐mortem human subjects (PMHS) subjected to a simulated 30 km/h frontal collision, and three male PMHS subjected to a simulated 30 km/h near‐side oblique collision. The eight PMHS approximated the 50th percentile male in both stature and mass and were restrained by a three‐point belt that incorporated a custom, force‐limited shoulder‐belt. During the tests, a motion capture system was used to obtain the 3D displacements of the head, T1, T8, L2, pelvis and shoulders relative to the vehicle buck. Additional locations on the anterior rib cage, including the sternum, upper left, upper right, lower left and lower right rib cage, were also measured using the motion capture system and were reported relative to a spinal coordinate system based on the T8 vertebrae in order to quantify chest deflection. These data were then used to develop three‐dimensional displacement corridors to quantify the whole‐body kinematic response of restrained PMHS. The provided response corridors will be immediately useful for efforts to evaluate or enhance the kinematic performance of Anthropomorphic Test Devices (ATDs) and computational models. Differences in the test conditions were seen in the lateral 3D displacements with the oblique tests having higher displacements due to the lateral component of the buck acceleration.
