Experiences in reverse-engineering of a finite element automobile crash model

摘要

The experiences encountered during the development, modification, and refinement of a finite element model of a four-door sedan are described. Single model is developed that can be successfully used in computational simulations of full frontal, offset frontal, side, and oblique car-to-car impacts. The simula- tion results are validate with test data of actual vehicles. The validation and computational simulations using the model show it to be computationally stable, reliable, repeatable, and useful as crash partner for other vehicles.
