| 摘 要： | 基于乘用车整车侧方碰撞分析,研究了车门板金件强度和厚度合理设计,以在保证安全性前提下使车门达到轻量化。对车门板金件不同强度和厚度方案的可变形壁障侧碰、侧壁柱撞仿真计算和结果分析表明,车门板金件厚度和强度变化对柱撞安全性变化不敏感;车门中部加强板不宜采用过强结构;车门内板强度和厚度是影响车门侵入量的关键因素。目前,绝大多数车门通过板金件强度和厚度的合理设计,可以在保证安全性的同时实现车门减重10%以上的目标。

| Abstract: | The lateral collision of a car is analyzed in this paper and the strength and design of its deformable barrier and columns are considered. The conditions of the simulation are the same as in the European New Car Assessment Programme (Eruo-NCAP). The influence of the strength and thickness of the door sheet on the safety of the car is discussed and analyzed. The result suggests that the strength and the thickness of the door sheet metal parts are not the key for safety in side impact crash of lateral columns... |
