Economical Occupant/Seat Restraint Model: Integration of ATB and LS- DYNA3D

摘要

The project objective was to integrate rigid body dynamics software ATB from the Air Force and three-dimensional nonlinear dynamic finite elements software LS-DYNA from LSTC Inc. This combination of existing software allows deformation and stress analysis in addition to rigid body motion within the same system. The purpose was to produce a new tool for integrated modeling and simulation of human body dynamic response in crashes and other hazardous situations. The resulting commercial product, marketed by LSTC Inc., can be used to support design of improved human-safety restraint systems for the aircraft and automobile industries.
