Extended Validation of the Finite Element Model for the 2010 Toyota Yaris Passenger Sedan (MASH 1100kg Vehicle)

A finite element (FE) model based on a 2010 Toyota Yaris passenger sedan was developed through the process of reverse engineering at the National Crash Analysis Center of The George Washington University. The resulting FE vehicle model has 974,383 elements, without the interior components or restraint systems. This detailed FE model was constructed to include full functional capabilities of the suspension and steering subsystems. This model was validated by comparing the simulation of the New Car Assessment Program frontal wall impact with actual data from National Highway Traffic Safety Administration tests for comparable vehicles. Acceptable results of the initial validation led to the release of the FE model. Subsequently, validation efforts continued with comparisons to data from other full frontal wall and offset deformable barrier impacts. Simulation results compared well to data from these tests. Finally, model robustness was demonstrated by additional simulations of centerline pole impacts, full front and offset head-on collisions into a Chevrolet Silverado, and damage comparisons for impacts at varying speeds. The simulations executed without error in these runs and the results reflected the expected responses and consistency with varying parameters. This led to the conclusions that the model was robust across various impact scenarios.
