摘要

为了获得汽车安全气囊仿真技术的精确度和可行性

建立了帘式气囊仿真模型

集成了侧碰撞系统模型。采用拓扑映射原理进行模型节点坐标转换

从而实现了帘式气囊有限元卷折网格的自动生成和帘式气囊在任意管状结构内的卷折成型; 使用MADYMO软件提供的均压法以及Dyna欧拉法、粒子法

依据卷折模型

对气囊展开过程的模拟结果进行了检验; 通过将帘式气囊模型、假人模型、车身侧面接触结构面进行集成

建立了带安全气囊的侧碰撞分析模型。通过3种类型侧碰撞工况的计算和试验对比

表明所建侧碰撞仿真模型能够真实地反映人体损伤情况。所建模型下的帘式安全气囊能够很好地保护乘员安全

可以有效地应用于汽车前期开发。

Abstract

To acquire the accuracy and feasibility of simulation method for automobile airbag

a curtain airbag FE model

including vehicle occupant safety system of side impact modeling

was established. The auto-meshing of folded curtain airbag was realized

and curtain airbag mesh among any type of tube cross section was generated following the topology mapping theory to make mesh nodes coordinate be transformed. Three kinds of methodology(pressure method of MADYMO

ALE gas method and particle method of Dyna)were compared by simulating airbag deployment of the folding model. The side impact analysis model with airbags was constructed by integrating the curtain airbag model

dummy

and body side contact surface. The comparison between calculation of three types of side impact conditions and tests indicates that the model of side impact simulation can accurately reflect human injury. The curtain airbag can more effectively protect passenger and facilitate early-stage design of automobiles.
