Using ATB in Collision Reconstruction 950131

The Articulated Total Body (ATB) computer program, sometimes referred to as the Crash Victim Simulator (CVS), is a powerful tool to aid in studying occupant kinematics in motor vehicle collisions. There are many options available within the ATB/CVS model and associated utility programs, such as GEBOD, which allow an analyst to model specific collisions and occupants. This paper discusses ATB/CVS as a tool for use in collision reconstruction. Specific examples are presented in developing a crash pulse from vehicle simulation programs such as EDSMAC, SMAC, HVOSM, etc. Techniques are also presented for modelling other moveable objects within the occupant environment, such as a seat back, steering column, or intrusion into the occupant compartment. A series of programs to aid in setting up an ATB data file, the CAL-3D Users Convenience Package, is also discussed.
