The simulation of parachute inflation process based on LS-DYNA software

摘要: 文章基于LS-DYNA软件对降落伞的充气过程进行了数值模拟，得到了降落伞的充气时间和投影面积变化的规律，验证了使用LS-DYNA软件数值模拟降落伞充气过程的可行性，提出了一种新的数值模拟降落伞充气过程的分析方法。

Abstract: Based on LS-DYNA software, the parachute inflation process is simulated in this paper, to obtain the relation between the inflation time and the project area which describes the inflation performance. The results show that the parachute inflation can be simulated by using LS-DYNA. A new method to analyze and simulate the parachute inflation process is proposed.
