WorldSID Advanced Harmonised Dummy for Side Impact








June1997 ISO/TC22/SC12/WG5 resolution followed by creation of Task Group & regional groups

  • June1997 ISO/TC22/SC12/WG5 resolution followed by creation of Task Group & regional groups

  • Oct.1998 Project Manager contracted

  • Jan.1999 Request for Quote for dummy design

  • Mar.1999 presentation of concepts

          • then creation of Design Team
  • Sep.1999 completion of design specification

  • June2000 sign off of dummy design



Sep.2000 assembly of prototype

  • Sep.2000 assembly of prototype

  • Dec.2000 delivery of prototype

  • Dec.2000 first crash tests and WorldSID Workshop

  • Jan.2001 evaluation of prototype biofidelity

  • Jun.2001 identification of initial modifications







  • Anthropometry

  • 50th percentile male

  • overall height: 1753 mm

  • seated height: 911 mm

  • total mass: 77,3 kg

  • Complies with UMTRI anthropometry

  • data for adult crash test dummies

  • Biofidelity

  • Goal: ‘Good’ to ‘Excellent’ on ISO TR9790 scale





Thorax, Shoulder, Abdomen



Lumbar Spine









7 DAS modules in dummy

  • 7 DAS modules in dummy

  • 0ver 200 channels available

  • Signal

  • conditioning

  • moved to the sensor.

  • Distributed, modular

  • data acquisition.

  • Drastically reduced wire

  • bundles inside dummy.

  • Umbilical from dummy is for power, com, and trigger.





ISO Rating (from TR 9790)

  • Response completely inside corridor B = 10

  • Response within one corridor width outside corridor B = 5

  • Response more than one corridor width outside corridor B = 0

  • Mean score for each body segment

  • After weighting body segments, mean of body segments = overall 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



Summary – Prototype Biofidelity Evaluation



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
