In the EC FP6 Integrated Project Advanced Protection Systems, APROSYS, the first WorldSID small female prototype was developed and evaluated by BASt, FTSS, INRETS, TRL and UPM-INSIA during 2006 and 2007. Results were presented at the ESV 2007 conference (Been et al., 2007). With the prototype dummy scoring a biofidelity rating higher than 6.7 out of 10 according to ISO/TR9790, the results were very promising. Also opportunities for further development were identified by the evaluation group.
A revised prototype, Revision1, was subsequently developed in the 2007-2008 period to address comments from the evaluation group. The Revision1 dummy includes changes in the half arms and the suit (anthropometry and arm biomechanics), the thorax and abdomen ribs and sternum (rib durability), the abdomen/lumbar area and the lower legs (mass distribution). Also a two-dimensional chest deflection measurement system was developed to measure deflection in both lateral and anterior-posterior direction to improve oblique thorax loading sensitivity. Two Revision1 prototype dummies have now been evaluated by FTSS, TRL, UPM-INSIA and BASt. The updated prototype dummies were subjected to an extensive matrix of biomechanical tests, such as full body pendulum tests and lateral sled impact tests as specified by Wayne State University, Heidelberg University and Medical College of Wisconsin.
The results indicated a significant improvement of dummy biofidelity. The overall dummy biofidelity in the ISO rating system has significantly improved from 6.7 to 7.6 on a scale between 0-10. The small female WorldSID has now obtained the same biofidelity rating as the WorldSID mid size male dummy. Also repeatability improved with respect to the prototype. In conclusion the recommended updates were all executed and all successfully contributed in achieving improved performance of the dummy.
