Correlation of Strain and Loads Measured in the Long Bones with Observed Kinematics of the Lower Limb during Vehicle-Pedestrian Impacts

In this study the loads in the long bones of the lower extremities during vehicle-pedestrian impact tests were determined and load data were correlated with observed kinematics in an effort to understand how stature and vehicle shape influence pedestrian response. Post mortem human surrogates (PMHS) in mid-stance gait were struck laterally at 40 km/h by a large sedan and a small multi-purpose vehicle (MPV). While peak axial forces were consistent for both the vehicles and ranged from 1 kN to 3 kN, bending moments in the right lower extremity exceeded 300 Nm in the sedan impacts but were substantially lower in impacts with the MPV. Stature differences caused variations in hip and knee impact locations relative to the hood edge and bumper of each vehicle that may have been a contributing factor resulting in more severe struck-side lower extremity injuries in the tall subject tested with the MPV, and more severe struck-side lower extremity injuries in the shorter subject tested with the sedan.
