Using ATB Under the HVE Environment

The Articulated Total Body (ATB) program has been used to study occupant kinematics in motor vehicle collisions for several years. The ATB model is a complex 3-dimensional lumped-mass model available for many different computer systems, including the personal computer, and requires formatted data files for the data input. A new version of this model, Graphical Articulated Total Body (GATB), has been developed to be operated under the HVE (Human, Vehicle, Environment) computer environment. The GATB program uses the graphical system built into HVE. This aids in set up and execution of the model to study human occupants in motor vehicle collisions. This paper addresses the integration of the ATB model with the HVE environment and includes a validation study comparing the GATB results to those of the ATB program.
