  1. Evaluation of ES-2by theOccupant Safety Research Partnershipof USCAR presented by Annette L. Irwin representing the Alliance of Automobile Manufacturers and the Organisation Internationale des Constructeurs d’Automobiles

  2. Background • Occupant Safety Research Partnership of USCAR Conducted Tests with ES-2 • Full-Scale Vehicle Tests • Biofidelity Tests of ISO TR 9790 • Results Published in 46th Stapp • Byrnes, et al., “ES-2 Dummy Biomechanical Responses,” Paper 2002-22-0018

  3. Purpose • To Evaluate • Modifications from EuroSID-1 to ES-2 • Biofidelity • Left-to-Right Symmetry • Repeatability • Reproducibility

  4. Full-Scale Testing • FMVSS 214 Configuration at 54 km/h • 2 Small Sedans • EuroSID-1 Driver & Left Rear Passenger • ES-2 Driver & Left Rear Passenger • 2 Large Sedans • EuroSID-1 Driver & Left Rear Passenger • ES-2 Driver & Left Rear Passenger

  5. Results of Full-Scale Testing WithSmall Sedan • EuroSID-1 Exhibited Rib Binding • ES-2 Did Not Exhibit Rib Binding • ES-2 Exhibited Rib Oscillation

  6. Results of Full-Scale Testing With Large Sedan • EuroSID-1 Exhibited Pubic “Noise” Spike • ES-2 Did Not Exhibit Pubic “Noise” Spike

  7. Biofidelity Testing • ISO TR 9790 (1999) • 23 Drop, Pendulum & Sled Tests • Assess Biofidelity of the Head, Neck, Shoulder, Thorax, Abdomen, and Pelvis • 3 to 6 Repeat Tests Conducted • Some Tests Conducted on Both Sides • Some Tests Conducted on Two Different ES-2 Dummies

  21. Results of Biofidelity Testing • Overall Biofidelity Rated Only Fair • Neck, Shoulder & Thorax Were Less Biofidelic Than EuroSID-1 • Repeatability Acceptable • Left-to-Right Symmetry Acceptable • Reproducibility Not Acceptable

  26. Conclusions • Rib Binding Was Not Observed in Limited Tests With ES-2 • Pubic “Noise” Spikes Were Not Observed in Limited Tests With ES-2 • Rib Oscillations Were Observed With ES-2

  27. Conclusions - continued • Overall ES-2 Was Not Biofidelic • Rated Only Fair • Repeatability, Left-to-Right Symmetry, and Durability Were Acceptable • Reproducibility Was Not Acceptable • Every Body Region of ES-2 is Less Biofidelic Than WorldSID Prototype
