1 Evaluation of the new certification test procedures Christian Gehre

2 Christian Gehre, PDB Upper neck moment My Poor reproducibility of the BioRID in sled tests Acceptable reproducibility in the old certification test Old certification test could not distinguish between dummy specimen Hard bucket seat, 16 kph pulseOld certification test Dummy D006 Dummy D007

3 Christian Gehre, PDB Test matrix Dummy D006 & D007 w/o head rest, standard probe Hard bucket seat Adjustment of the dummy w/o head rest, standard probe w/ head rest, standard probe jacket test, standard probe Hard bucket seat w/o head rest, standard probe w/ head rest, standard probe w/ head rest, heavy probe Status Adjustment Verification

4 Christian Gehre, PDB Results certification tests Upper neck moment My Standard probeHeavy probe w/ Head rest No difference between dummies w/o Head rest No difference between dummies Torso jacket No difference between dummies

5 Dummy artefact Christian Gehre

6 Christian Gehre, PDB Dummy artefacts Design of the dummy Upper torso jacket boltsInner plates

7 Christian Gehre, PDB Dummy artefacts Kinematics Hard bucket seat Vehicle seat Load path shoulder to spineInteraction between bolts and plates (hard bucket seat) w/ bolts w/o bolts

8 Christian Gehre, PDB Dummy artefacts Results – Testing (dummy D078) Positive neck force is mainly caused by the load applied via the upper torso jacket bolts incl. the interaction with the inner shoulder plates –Change of Nkm by 11% and of NIC by 2% Baseline w/o upper torso jacket bolts Upper neck Fx Upper Neck My Head contact
