摘　　要：针对安全气囊展开仿真,从理论发展和应用的角度综述了几种常用的数字仿真方法,首先研究了用于IP(In-Position)乘员与气囊接触分析的控制体积方法(Control Volume,CV),分析了其对OOP(Out-Of-Position)情况仿真的不足;然后研究了可对OOP情况建模的、基于计算流体力学(Computational Fluid Dynamics,CFD)的仿真方法,以及近年来新开发的粒子法(Corpuscular Method,CPM),并总结了近年来的相关研究结果。文章指出了气囊展开仿真工作的研究方向。Several common simulation methods for airbag deployment analysis are summarized from the points of theory and application. Firstly, the traditional CV（Control Volume）method that has been developed and utilized for IP（In-Posi- tion）occupant analysis is studied, and its inefficiency for OOP （Out-Of-Position）occupant interaction simulation is ana- lyzed. Then the simulation technique based on CFD （Computational Fluid Dynamics）and a recently developed CPM（Cor- puscular Method）method are studied, both of which can model the OOP occupant interaction. Related research results of these methods are summarized. Finally, the review addresses a number of open problems and suggests a few prospective topics in a near future.
