| 摘 要： | 利用已知的伞衣织物透气量与压差曲线计算得到了表征伞衣织物透气性能的两个主要参数一粘性系数和惯性系数，并运用LS—DYNA软件的流固耦合算法对其进行了验证，这对以后仿真降落伞充气过程有一定的参考作用。

| Abstract: | According to the air permeability-differential pressure curves of the canopy,the viscous and inertia parameters for the permeability of the parachute canopy were acquired in the paper.The results by control algorithm for FSI using the viscous and inertia parameters in the LS-DYNA were accurate.The studies offered a reference for simulation of the parachute inflation in future. |
