Side Impact Dummy Enhancements for Improved Occupant Protection forthe Year 2000 and Beyond


The basis of this work lies in earlier reviews by ISO and the European Experimental Safety Committee which both recommend a set of requirements to assess the biofidelity of a midsize male side impact dummy. The results of this work are biofidelity targets for head, neck, thorax, shoulders, pelvis and abdomen that can be used to assess the biofidelity of the dummies in side impact and to derive calibration procedures. At a worldwide level, the recommendations have been discussed in the frame of the IHRA Biomechanics working group (International Harmonized Research Agenda) and are part of a new worldwide harmonised biofidelic requirements for side impact, applied for the advanced, harmonized side impact dummy WorldSID. The requirements will form a reference for both governments and the automotive industry (the end-users) regarding human impact behavior in side impact, the main benefits being that this set will be globally agreed upon and considered state-of-the-art in biomechanics. Application in other transport sectors concerned about occupant safety (such as aerospace and rail) is feasible.
Injury risk functions for EUROSID-1 were published by ISO/TC22/SC12/WG6 on 'Biomechanics'. This result concentrated on a detailed evaluation of the statistical methods and PMHS data that could be used to develop injury risk curves for a side impact dummy. This was designed to enable a thorough evaluation of the injury risk curves proposed by ISO WG6, leading to a recommendation on the use or otherwise of the ISO curves. In addition, recommendations were also made on the PMHS data that would be suitable for use in the derivation of injury risk curves. This eliminated some of the data used by ISO WG6 in the derivation of their injury risk curves. The results provide firm foundations for the development of injury risk criteria for current and future side impact dummies and will be of particular value in establishing new criteria for WorldSID. The end-users of this results are mainly governments and/or government associated research institutes responsible for setting or recommending the injury limits in regulation. Application in other transport sectors concerned about occupant safety (such as aerospace and rail) is feasible.
