摘要
本文件报告了对汽车结构部件的耐撞性进行的数值和实验研究。特别是在内部设计的撞击试验装置上对新型高强度钢制成的挡风玻璃 A 柱进行了试验，以再现车辆侧面撞击的效果。与此同时，还使用显式有限元代码 LS-DYNA 进行了数值模拟，并考虑了带有损伤的不同弹塑性材料构成规律。数值结果与实验结果之间的比较显示出令人满意的相关性，GISSMO 模型提供了良好的相关性，所需的计算量也相对较低。
Numerical-experimental study on the crashworthiness of a windshield A-pillar
This document reports a numerical and experimental crashworthiness study of a vehicle structural component. Particularly, a windshield A-pillar made of a novel high-strength steel was tested on an apparatus for impact tests that was in-house designed so as to reproduce the effects of a vehicle side impact crash. In parallel, numerical simulations were performed using the explicit finite element code LS-DYNA, considering different elastic-plastic material constitutive laws with damage. A comparison between numerical and experimental outcomes demonstrated a satisfactory correlation, with the GISSMO model that provided a good correlation and needed a relatively low computational effort.
