| 中文摘要: |
| 以冲压式快速空投气囊为研究对象,对冲压式快速空投气囊的垂直着陆缓冲过程进行了仿真。首先使用Solidworks 软件建立了气囊的仿真模型,然后使用Ansys/ LS-Dyna 有限元分析软件,仿真研究了冲压式快速空投气囊着陆过程中气囊的应力应变的动态参数。研究得出了气囊在着陆缓冲过程中受到的最大应力值,以及出现最大应变的区域,从而更好地确定空投物体的质量,并且可以针对性地加强对气囊应力应变较大区域的防护,防止气囊在冲击过程中被破坏。 |
| 英文摘要: |
| Punched quick airdrop airbag was taken as research object and the vertical landing process of the airbag was simulated. A simulation model of the airbag was established using Solidworks software and simulation was carried out using finite element analysis software Ansys/ LS-Dyna. The dynamic parameters, such as stress and strain of the airbag, were studied. The maximal value of the airbag and the area where the maximum strain occurs during landing process was obtained. As a result, the mass of airdrop body can be better specified, and the protection of the area with great stress and strain can be strengthened accordingly. |
