A new finite element model of a human dummy should enable car designers reduce the risk of whiplash injuries
 .
The Abaqus BioRid II (Biofidelic Rear Impact Dummy II) represents the complex neck and spine construction of the real world BioRid II dummy. The model has been developed and validated in cooperation with the German Association for Research in Automobile Technology The software model, in combination with the real dummy, will be used to evaluate the performance of complete seats, including head restraint systems designed to minimise whiplash injuries.
"Realistic simulation is proving to be ever more critical in the development of our seating systems to address market requirements and satisfy regulatory issues,” according to Laurent Guerin, simulation methods manager of the automotive seating product group at Faurecia, Europe’s second largest automotive equipment supplier. “BioRid II is providing accurate predictions and correlation against physical test results, and we are incorporating its usage as an integral part of our product development process. Such simulation capabilities enhance effectiveness in designing and manufacturing seats and head restraints that can reduce whiplash injuries in rear impact crashes.”
The German Association for Research in Automobile Technology promotes scientific research of automobile performance, safety, materials, and efficiency. Member companies in the working group for crash and occupant safety simulation include Audi, BMW, CRH, Daimler, JCI, Karmann, Keiper, Opel, Porsche, and Volkswagen.
