Vehicle Interior and Restraints Modeling Development of Full Vehicle Finite Element Model Including Vehicle Interior and Occupant Restraints Systems for Occupant Safety Analysis Using THOR Dummies

NHTSA awarded a contract to EDAG, Inc., to develop a full vehicle finite element model including a vehicle interior and occupant restraint systems for the driver and front-seat passenger. The resulting finite element model represents a model year (MY) 2014 Honda Accord mid-size sedan. This report documents the work done to fulfill the requirements of this Task Order. Specifically, the predicted results demonstrate that the baseline vehicle FEM model correlates well with the safety performance exhibited in full vehicle test results for vehicle acceleration and intrusion responses in NCAP frontal, IIHS moderate overlap, IIHS small overlap test procedures, and left and right NHTSA oblique frontal tests. The vehicle FEM also includes test device for human occupant restraint (THOR) 50th percentile male frontal dummy models in the driver and front passenger seats. Simulation results using these dummies demonstrate the performance in left and right NHTSA oblique frontal crash tests. Occupant kinematics, belt loads, and injury criteria results are compared against the existing test results. Overall the FEM simulation results compare well with test results for THOR dummy accelerations and injury criteria. The FEM simulation results using comparison GHBMC model dummies compare well with test results and FEM of THOR dummies. The computer run time, however, is much higher with GHBMC dummies compared with the THOR model.
