Analysis of EUROSID Biofidelity

Kallieris, Dimitrios / Hoefs, Rainer

Results from 15 side impact tests with EUROSID are reported and compared with results from 58 postmortem human subjects (PMHS). In this test series a CCMC moving deformable barrier impacted an Opel Kadett body in white under a 90° impact angle. Impact speeds were 40 km/h, 45 km/h, 50 km/h.The main goal of this research project was to find out to what extent the EUROSID is able to predict injuries which were obtained under identical test conditions using PMHS. Statistical methods described in former publications were used to calculate prediction relations derived from measured data.The body regions to be concentrated on according to PMHS tests were thorax, abdomen, and trunk of the EUROSID. Measurements taken on the dummy indicated major problems regarding interpretation of results: in some tests rib deflection was higher with 40 km/h than with 50 km/h. The abdominal switches frequently indicated high forces at 40 km/h impact speed whereas they did only once at 50 km/h.Measurements which are different from standard EUROSID measurement equipment seem to have a better potential for prediction of thoracic and abdominal injuries. Proposals for prediction of injury severity are made based on statistical analysis. TTI* and V*C are calculated and analysed with respect to their prediction quality.
