Abstract
缓冲气囊具有重量轻、可折叠和成本低廉等优点，被广泛应用在交通工具乘员安全、货物空投、无人机回收及深空探测等领域。本文首先介绍了各类缓冲气囊并总结了缓冲气囊的研究方法，包括实验分析、物理模型分析以及有限元仿真。然后对比分析了有限元仿真中的CV法和ALE法，并指出了两种方法的优缺点。 The buffering airbag is lightweight, collapsible and low cost, which is widely used in the field of transport safety of the crew, cargo airdrop, UAV recovery and deep space exploration. Firstly this article presents the various kinds of buffering airbags and summarizes the research methods of the buffering airbags, which include laboratory analysis, physical model analysis and finite element simulation. Secondly the CV method and the ALE method are compared in this article, and the advantages and the disadvantages of the two methods are pointed out.
