DESIGN AND EVALUATION OF THE WORLDSID PROTOTYPE DUMMY

The WorldSID is a new, advanced Worldwide Side Impact Dummy that has the anthropometry of a mid-sized adult male. It has a mass of 77.3 kg, a standing height of 1753 mm and a seated height of 911 mm. Almost every body region is a new, innovative design, setting the WorldSID apart from all existing side impact dummies. It incorporates over 200 available data channels, in-dummy wiring, and an in-dummy data acquisition system (DAS). The dummy is designed to be used for research and future harmonized side impact test procedures as defined by the International Harmonized Research Activities (IHRA) and other organizations. It is expected to have a biofidelity classification of “good” to “excellent” using the International Organization for Standardization (ISO) dummy classification scale. The WorldSID will be the basis for the future development of a side impact dummy family. The WorldSID project is run under the auspices of the ISO working group on Anthropomorphic Test Devices -- ISO/TC22/SC12/WG5. Worldwide vehicle manufacturers and governmental bodies have sponsored its development. A design team of worldwide dummy manufacturers, instrumentation manufacturers and research organizations was formed to design, develop and fabricate the prototype.

This paper will provide the general design requirements for the WorldSID dummy and a description of each of the critical body regions. A description of the unique instrumentation found in the WorldSID dummy and the data from the biofidelity testing conducted to date will also be presented.
