摘　　要：侧面碰撞是如今汽车碰撞事故中常见的类型,配备侧气囊可以有效减少乘员在侧面碰撞中受到的伤害。文章利用计算机辅助分析技术,建立侧气囊静态展开仿真模型,分别应用粒子法(CPM法)和控制体积法(CV法)进行侧气囊静态展开模拟,对比试验结果表明:展开过程中,采用CPM方法的侧气囊模型比采用CV法更加接近试验状态,CPM法可以比较精确地模拟气囊的展开过程,更有利于安全气囊开发工作。Side impact is a usual type of vehicle crash accident in recent years,side airbag is a important device to improvesafety of occupants.In this paper,a simulation model is created to simulate the deployment process of folded airbag byadopting corpuscular particle method(CPM)and control volume(CV)method respectively.Through the comparison withtest video indicates that CPM result is more closer to the test results.CPM can simulate the status of deploymentaccurately.It is better for the development of safety airbag.
