WorldSID Advanced Harmonized Dummy for Side Impact Martin Page C.E.E.S.A.R. (speaking to LAB) for the benefit of the WorldSID Task Group Presentation to the GRSP December 2001

Slide 2

Background: The WorldSID Project under support of ISO TC22/SC12/WG5 Goal to supplant all current grown-up side effect fakers with a solitary, profoundly biofidelic show worthy to all clients Government, industry & specialists cooperating Large decision of instrumentation Presentation to the GRSP December 2001

Slide 3

Project Organization ISO TC22/SC12/WG5 Working Group - Anthropomorphic Test Devices IHRA WorldSID Task Group Co-appointment all inclusive governments Project Manager Design Team European Advisory Group Americas Advisory Group Asia-Pacific Advisory Group Presentation to the GRSP December 2001

Slide 4

1998 1999 2000 2001 2002 2003 2004 Set up program and create particulars Pre-generation sham assessment Final determinations Prototype assessment Release into open area Prototype advancement Production sham improvement Pre-creation sham advancement Project Timeline Presentation to the GRSP December 2001

Slide 5

June1997 ISO/TC22/SC12/WG5 resolution took after by formation of Task Group & territorial gatherings Oct.1998 Project Manager contracted Jan.1999 Request for Quote for sham plan Mar.1999 presentation of ideas then making of Design Team Sep.1999 completion of outline detail June2000 sign off of sham plan Milestones Presentation to the GRSP December 2001

Slide 6

Sep.2000 assembly of model Dec.2000 delivery of model Dec.2000 first crash tests and WorldSID Workshop Jan.2001 evaluation of model biofidelity Jun.2001 identification of starting adjustments took after by use of alterations … Milestones (cont'd) Presentation to the GRSP December 2001

Slide 7

Next Steps Re-testing of changed model Development of pre-generation sham Sale of approx. 9 pre-prod'n fakers to back improvement Comprehensive assessment of pre-prod'n fakers around the globe Final improvement Release of definite outline into open space Presentation to the GRSP December 2001

Slide 8

Description of Dummy propelled plan Presentation to the GRSP December 2001

Slide 9

Anthropometry 50th percentile male overall height: 1753 mm seated height: 911 mm total mass: 77,3 kg Complies with UMTRI anthropometry information for grown-up crash test fakers Biofidelity Goal: "Great" to "Incredible" on ISO TR9790 scale Presentation to the GRSP December 2001

Slide 10

Head One-piece polymer skull Seamless skin Frontal & horizontal biofidelity Instrumentation center Neck cover Presentation to the GRSP December 2001

Slide 11

Outer rib 75mm diversion IR-TRACC raise Inner rib Thorax, Shoulder, Abdomen Presentation to the GRSP December 2001

Slide 12

New idea for de-coupling of pelvis and thorax Load cell Lumbar Spine Presentation to the GRSP December 2001

Slide 13

Pelvis no shrouded stack ways raise Sacro-iliac load cells lumbar load cell Femur neck stack cells pubic load cell Presentation to the GRSP December 2001

Slide 14

Lower Extremities Femoral neck stack cell DAS module box Knee pivot sensor Knee contact stack cells Leg stack cell Fully instrumented Specific outline Presentation to the GRSP December 2001

Slide 15

3-hub Shoulder LC 6-hub Universal Arm LC 2-hub Elbow LC (Mx,My) Triaxial Accelerometer Elbow Angular Sensor Upper Extremity Half arm Instrumented arm Presentation to the GRSP December 2001

Slide 16

Optional In-Dummy Data Acquisition 7 DAS modules in sham 0ver 200 channels accessible Signal conditioning moved to the sensor. Circulated, particular data obtaining. Definitely diminished wire bundles inside sham. Umbilical from sham is for power, com, and trigger. Introduction to the GRSP December 2001

Slide 17

Biofidelity Evaluation of model All ISO TR 9790 tests performed Testing by Transport Canada & Medical College Wisconsin (supported NHTSA) Tests on right and left side 3 tests for each side Reported at 2001 Stapp Conference: WorldSID model Dummy Biomechanical Responses , Cesari et al. Introduction to the GRSP December 2001

Slide 18

ISO Rating (from TR 9790) Response totally inside hallway B = 10 Response inside one passage width outside passageway B = 5 Response more than one hallway width outside hall B = 0 Mean score for each body section After weighting body fragments, mean of body portions = general B Excellent Biofidelity: 8,6 £ B < 10,0 Good Biofidelity: 6,5 £ B < 8,6 Fair Biofidelity: 4,4 £ B < 6,5 Marginal Biofidelity: 2,6 £ B < 4,4 Unacceptable Biofidelity: 0,0 £ B < 2,6 Presentation to the GRSP December 2001

Slide 19

Summary – Prototype Biofidelity Evaluation Bendjellal et al, ESV 13 Excellent Biofidelity: 8,6 £ B < 10,0 Good Biofidelity: 6,5 £ B < 8,6 Fair Biofidelity: 4,4 £ B < 6,5 Presentation to the GRSP December 2001

Slide 20

Summary of Results Head: great parallel biofidelity – frontal reaction is second priority however just minor alteration to meet target Neck: - hard to meet both sidelong and frontal reaction requirements -Response affected by shoulder – More work to be done Shoulder: to be solidified – ought to effortlessly meet target Thorax: meets target Abdomen: goal ought to be met after adjustment Pelvis: gives off an impression of being too firm -Check bone/tissue mass appropriation -Design might be contradictory with TR 9790 sled tests with cushioning Presentation to the GRSP December 2001

Slide 21

Repeatability Biofidelity assessment shows great repeatablity Durability Over 100 biofidelity tests + 2 full scale tests - only minor harm Presentation to the GRSP December 2001

Slide 22

Summary The execution of the WorldSID model sham has been extremely encouraging Development work is proceeding with Final sham discharge into open area and dispatch of generation sham expected on plan for 2004 Presentation to the GRSP December 2001
