Constructing the Model
The Global Human Body Models (GHBMC) is composed of 10 major automotive manufacturers and suppliers whose goal is to consolidate work in the field of model development to a united global effort over the next several years.
The research and development of these models is being conducted at 7 partner universities across the globe. As the lead center (integration center), Wake Forest University has recruited individuals to serve as templates for these models, collecting detailed measurements and medical images from which to construct the virtual models.
The group has developed a 50th percentile height and weight geometry and is developing computerized anatomy of 4 targeted individuals to represent the population at large, ranging in size from a 4 ft. 11 in. small female (5th percentile) to a 6 ft. 2 in. large male (95th percentile). Each geometrical model will contain over 400 body parts that are necessary to predict some of the most common injuries sustained in crashes.
The final computerized models will have over 2.5 million pieces that will allow engineers to extract data on how the body behaves in a crash. This data will help researchers estimate the risks of diverse injuries ranging from a broken femur to mild traumatic brain injury. The team expects to complete the first of these virtual models by the end of 2011, and the model could be in use by manufacturers as early as 2012.
