Side-impact collisions represent the second greatest cause of fatality in motor vehicle accidents. Side-impact airbags have been installed in recent model year vehicle due to its effectiveness in reducing passengers’ injuries and fatality rates. In meeting these requirements, simulations of folding and deploying airbags are very useful and are widely used. The paper presents a simulation method for the deploying airbags using three materials in different working conditions. Finite element analysis is primarily used to evaluate this concept. In these simulations, the gas flow is described by the conservation laws of mass, momentum, and energy. The numerical results indicate that the FE method in this paper is capable of capturing airbag deploying process accurately.

偏位情况下侧面安全气囊展开的数值分析

侧面碰撞是造成机动车事故死亡的第二大原因。由于其在减少乘客受伤和致死率方面的有效性，因此在最近的年度车型中已安装了侧面安全气囊。为了满足这些要求，折叠和展开安全气囊的模拟非常有用并且得到了广泛的应用。本文提出了一种使用三种材料在不同工作条件下展开安全气囊的模拟方法。有限元分析主要用于评估此概念。在这些模拟中，气流由质量，动量和能量的守恒定律描述。数值结果表明，本文的有限元方法能够准确地反映安全气囊的展开过程。
