Presentation to the GRSP December 2001 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 - 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 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 - 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
