Presentation from Mr Bortenschlager, PDB (GTR7-07-03): Mr Bortenschlager gave a presentation regarding the interaction of the shoulder of the BioRID dummy with the seat back/wings of the hard bucket seat used in the test programme presented above. It was indicated that both simulation and the test work presented showed a load path from the shoulder, via the T2 jacket bolt, that was larger in the hard bucket seat than a standard seat. This load path is not controlled by the certification tests. In dummy tests the upper neck Fx and My results changed markedly when the T2 bolt was removed, but with very little change in NIC. The shape of the seat back on the hard bucket seat and the standard seat was shown. The dummy spine did not appear to be in contact with the bucket seat, just the shoulders. The presentation concluded by asking whether this load path is biofidelic, and is the curvature of the seat back in the shoulder region responsible for WAD protection? |
