| 摘 要： | 为了分析轿车与行道树正碰事故再现过程,建立了一款市场上常见的微型轿车有限元模型并验证其有效性,选择白杨树作为碰撞对象,进行事故再现关键因素研究。以轿车前端主要变形区的四结构件:前保险杠、前保险杠内杠、引擎盖和水箱为分析对象。基于Pam-crash软件平台,设计正交试验来分析碰撞速度、碰撞位置及行道树直径对四结构件碰撞变形的影响。仿真实验结果显示:碰撞速度是碰撞变形的最主要影响因素;前保险杠内杠在保存事故信息方面优势明显,可以作为事故再现分析的主要对象。

| Abstract: | In order to analyze the reconstruction process of sedan-tree frontal collision accident,a commonly-used sedan finite element model is established and the effectiveness is verified.By selecting a poplar as the collision object,the key factors for reconstructing the accident are analyzed.The four main structural parts deformed in the front of a sedan,including front bumper,front inner bumper,water tank and engine cover,are selected as the analyzed objects.The impact of the collision velocity,collision locatio... |
