摘要：

零部件级耐撞性验证是进一步缩短整车项目开发周期的有效手段，但由于没有统一规范的技术标准，导致其评估对象和评估工况具有显著的多样性特征。为了寻找一套系统的零部件级验证方法，以整车侧面碰撞车身结构设计为例，根据零部件级模型的多样性，建立了零部件级仿真分析评估矩阵，并提出了B 柱耐撞性评估标准。从同一对象不同工况和同一工况不同对象两个角度，对各种零部件模型进行筛查比对，确定了采用准静态刚性平面挤压工况和侧围或B 柱模型进行零部件级的耐撞性验证。并对三款整车的B 柱结构设计进行了仿真分析。其结果与主观评价结果一致。

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.
