摘要：

侧气帘(CAB) 是提升车辆安全性的重要配置。该文使用Primer 软件中的均压法(CV) 与粒子
法(CPM) 两种方法，研究了侧气帘静爆展开过程。根据选择的内饰网格划分、侧气帘折叠、气囊起爆
等方式，搭建了侧气帘静爆仿真模型。用该模型仿真对比了均压法和粒子法的气帘展开过程，分析了
这两种方法对导向支架的影响，并对有导向支架和无导向支架两种工况进行了分析。结果表明：粒子
法搭建的侧气帘模型的展开过程，比均压法的更加接近于试验真实状态；通过增加侧气帘B 柱、C
柱导向支架，可引导气帘起爆的方向，避免气帘挤入内饰与车身的缝隙中，使侧气帘能够正常顺利地
展开。

Abstract:

Curtain airbag (CAB) is an important equipment to improve vehicle safety. This paper investigated
the deployment process of a CAB by using control volume method (CV) and corpuscular method (CPM) in
software Primer. A CAB deployment simulation model was established based on the selected trim meshing, the
CAB folding, and the CAB deployment. This model was used to simulate and compare the CAB deployment
process from both the CV and the CPM method and to analyze the effect of the two methods on oriented
brackets in two working conditions with or without having oriented brackets. The results show that the CAB
deployment process by using CPM method is more close to the real test conditions than the deployment process
by CV method. Therefore, by adding oriented brackets on B pillar and C pillar, can guide the direction of CAB
deployment and avoid moveing CAB into the gap between trim and car body, this leads CAB deploy normally
and smoothly.
