Injury thresholds and a measurement technique for the thigh and leg of a pedestrian

The new design of a modified lower limb of the Polar-II pedestrian dummy for enhanced biofidelity requires establishment of an alternative instrumentation to load cells. The objective of this study was to determine injury thresholds for the thigh and leg of the modified dummy, and to establish an alternative measurement technique. FE pedestrian impact simulations were run using full-body dummy and human models to determine injury thresholds for the dummy. Quasi-static mid-shaft 3-point bending tests of the modified femur and tibia were performed to compare bending moments calculated from strains with those from support forces to validate the measurement technique.
