Summary of ResultsSummary 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 responserequirements - Response influenced by shoulder– More work to be done
• Shoulder: to be stiffened – should easily meet objective• Thorax: meets objective• Abdomen: objective should be met after modification• Pelvis: appears to be too stiff
- Check bone/flesh mass distribution- Design may be incompatible with TR 9790 sled tests with
padding
