Virtual CRASH accident reconstruction software is used for accident reconstruction simulation analyses involving passenger vehicles, pedestrians, bicycles, motorcycles, commercial vehicles, and more. Virtual CRASH can be used for drawing scale diagrams, building 3D models, performing physics studies.

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.

- The program builds up and encourages good habits that will be used when driving a car. SimuRide was designed with the driver in mind. By practicing on a simulator, in addition to practicing in a real vehicle, students can calmly pick up necessary skills, gain the experience to feel comfortable.
- Accident simulation is similar to animation as far as the visual end product but the technique is slightly different. With a computer simulation, the program software includes a validated physics module that calculates and predicts the movements and/or post-collision dynamics of the vehicles depending on the set of initial conditions input.
Integrated Seat Belt Model Development

NHTSA funded the development of a Finite Element Model (FEM) of seat with integrated seat belts from a recent model passenger vehicle. The FEM include static tests to evaluate 2019 Honda Odyssey second row seat deformation and potential failure mechanisms. It also includes dynamic tests with appropriate ATDs to evaluate occupant kinematics and injury in high-severity front and rear impact crashes. All test data along with seat tear down measurements and component testing, factored into the development and validation of the FE model.
Adjustable Sled Test Buck for Multiple Seating Configurations
Car Accident Simulation Program Free Pdf
NHTSA’s Vehicle Research & Test Center designed and fabricated a sled buck to allow for occupant biomechanical response evaluations in both traditional and non-traditional seating configurations. Testing with this sled buck has included rear-facing, reclined seating scenarios using a 2019 Honda Odyssey second row seat with integrated belts (the FE model of that seat is also posted on this page). The CAD files for this sled buck are being provided to the public so that modelers can simulate the locations of the external (head restraint and seat back) force measurements from NHTSA tests with both ATDs and post-mortem human subjects (PMHS). Using these buck files together with the seat model provides an accurate representation of the NHTSA test environment so that ATD or human body models can be evaluated in the same conditions.
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.

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.
