Integration of Finite Element Analysis (LS-DYNA) with Rigid Body Dynamics (ATB) for Crash Simulation

This paper describes the Integration of ATB (Articulated Total Body), a rigid body dynamics program and LS-DYNA, a finite element analysis program for PC-based occupant/seat restraint modeling. The integration of ATB and LS-DYNA provides a single simulation tool with the advantages of each individual code. The results of several cases and validation are also described in detail. The output of the coupled software is found to be consistent with the output from the already validated ATB program.
