Abstract

A program is underway to develop and validate a high fidelity finite element model of a full size car for crashworthiness analysis. This study is part of an overall program to develop a set of detailed finite element models for various vehicles that represent the range of vehicle types currently on the road. These vehicle models can then be used to study how future light-weight vehicles will change the overall crash safety of the fleet.

The representative full-size car selected for this program was the Ford Crown Victoria. The model development required the tear-down and digitization of a vehicle to characterize the geometry and material testing to measure the mechanical properties. The digitized structural component surfaces were then used to generate the vehicle components in the finite element model.
