Anthropometry 50th percentile male overall height: 1753 mm seated height: 911 mm total mass: 77,3 kg Complies with UMTRI anthropometry data for adult crash test dummies Biofidelity Goal: ‘Good’ to ‘Excellent’ on ISO TR9790 scale
Thorax, Shoulder, Abdomen
Lumbar Spine
7 DAS modules in dummy 7 DAS modules in dummy 0ver 200 channels available Signal conditioning moved to the sensor. Distributed, modular data acquisition. bundles inside dummy. Umbilical from dummy is for power, com, and trigger.
ISO Rating (from TR 9790) Response completely inside corridor B = 10 Response within one corridor width outside corridor B = 5 Response more than one corridor width outside corridor B = 0 Mean score for each body segment After weighting body segments, mean of body segments = overall B Excellent Biofidelity: 8,6 B 10,0 Good Biofidelity: 6,5 B 8,6 Fair Biofidelity: 4,4 B 6,5 Marginal Biofidelity: 2,6 B 4,4 Unacceptable Biofidelity: 0,0 B 2,6
Summary of Results Head: good lateral biofidelity – frontal response is second priority but only minor modification to meet objective Neck: - difficult to meet both lateral and frontal response requirements – More work to be done Shoulder: to be stiffened – should easily meet objective Thorax: meets objective Abdomen: objective should be met after modification - Check bone/flesh mass distribution - Design may be incompatible with TR 9790 sled tests with padding
