Abstract:

The crashworthiness verification of components level is an effective method to further shorten the development cycle of vehicle project, but there is no uniform and normative technical standards, resulting in the assessment objects and load cases have significant diversity characteristics. In order to find a set of system verification method of components level, with the vehicle side impact body structure design as an example, the evaluation matrix of components level simulation analysis is established according to the diversity of the component level model, and the crashworthiness evaluation standard of B-pillar is put forward. From
the same object & different load cases, and the same load case & different objects in two different angles, it is identified that using the load case of quasi static and rigidity flat and the side body or B-pillar model to do the crashworthiness verification of components level by screening for various component level models. And, the B-pillar structure design of the three vehicle are analyzed using B-pillar verification model. The result is consistent with the subjective evaluation result.

Key words: automobile safety, automobile parts, B-pillar crashworthiness, vehicle development, evaluation matrix of simulation analysis, crashworthiness evaluation standard of B-pillar
