Modeling, Validation and Optimization of Car Side Impact

In this paper, a passenger cars side impact CAE model was built with LS-DYNA software according to Chinese New Car Assessment Program (C-NCAP), the model was correlated very well with the test based on the data of B pillar intrusion velocity and the deformation of B-pillar and door intrusion. In order to improve the performance for side impact, the optimization proposal was provided after analyzing the results. It is showed that the side impact performance of the car was enhanced significantly after the optimization implemented.
