| 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. |
