Crash Simulation Vehicle Models

Vehicle Interior and Restraint Modeling

EDAG, Inc., developed a full vehicle finite element model (FEM) including a vehicle interior and occupant restraint systems for the driver and front-seat passenger. The resulting FEM represents a model year (MY) 2014 Honda Accord mid-size sedan.  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.

Structural Countermeasure Research Program
The report by EDAG, Inc., describes necessary changes to a vehicle’s structure to reduce occupant compartment intrusion from NHTSA’s oblique offset frontal crash condition, using finite element simulations of vehicle models in NCAP frontal, IIHS moderate offset, and IIHS small overlap test conditions. The study considered structural reinforcement of driver and passenger sides of the vehicle for left- and right-side oblique offset impacts. The baseline simulation crash tests were performed on the 2014 Honda Accord and 2014 Silverado 1500.

Additional information

CARB contracted Lotus Engineering Inc. to validate the safety of a low-mass vehicle body-in-white such as the crossover vehicle described in Lotus’ 2010 lightweight vehicle study, An Assessment of Mass Reduction Opportunities for a 2017-2020 Model Year Vehicle Program. The baseline, low option and high option FEA models were developed to support this study.

The following models were developed by George Washington University National Crash Analysis Center and used in support of several NHTSA programs.  

Cheverolet Silverado

Ford Explorer

Ford Taurus

Honda Accord

Toyota Venza

Toyota Yaris
