A good crash test dummy takes a lot of hard work


Until now, General Motor had built the best crash test dummies. The specialists are now doing a research trying to determine exactly how crash victims are hurt in rear impacts and this way developing better safety systems. The new dummy is actually called BioRID and it was designed for seat restraint assessment, in Sweden and the Chalmers University in Gothenburg. What makes it that special? Well, it has a spine with 24 vertebra simulators. These allow the dummy to sit naturally and it also simulates humanlike neck movements in rear-end collisions. Of course, to be approved the new BioRID dummy needs to be tested over and over again and the results need to be reproducible. This is actually demanding to the design and evaluation of vehicle safety.



GM specialists have developed a safety test that in the same time evaluated the BioRID dummies. The carmakers involved were Porsche, Daimler, Volkswagen, Ford and Chrysler. The tests involved the dummies in a low-speed rear impact simulation in almost identical seats. The specialists have collected measurements of crash forces on areal like the lower and upper neck. The results were then compared to the results obtained by other carmaker laboratories in Europe. General Motors uses a wide range of adult male and female, children sized crash test dummies that contain very complex data collection sensors, capable of offering status reports 10.000 times / second. The date helps engineers develop new ways of developing safety systems for the vehicles. Models like the 2012 Chevrolet, Cadillac, Buick and GMC have received the name of 2012 Top Safety Picks by the IIHS. The efforts of the specialists seem to have very good results. The BioRID test will benefit all carmakers involves as for sure all want to offer safer vehicles to their customers.
