ABSTRACT: Based on
the basic principle of vehicle crash analysis using the finite element method,
a car finite element model was built by using Hypermesh software. To simulate
the front collision test of the car, the LS-DYNA software is adopted to
calculate the deformation of the car and the acceleration time history curves
during the crashing process; the anti-impact capability of the car is evaluated
from this simulation. The results demonstrate that the improvement of local
structure can promote the crashworthiness of the car, but the further
improvement needs a major change of the car structure.
