Numerical simulation of parachute opening process in finite mass situation

  • 摘要: 为了模拟降落伞减速系统在有限质量情况下的三维动态开伞过程,以典型平面圆形伞C9伞为例,采用LS-DYNA基于有限元理论的ALE流固耦合方法对其充气至稳降过程进行研究,并用空投试验验证计算结果。计算获得了结构、流场动态变化,还获得了反映减速特性的载荷速度、加速度变化情况,分析了降落伞工作过程中危险截面、过载及外形之间的对应关系。研究结果表明:ALE法能够预测伞衣展开过程中减速特性以及危险截面,数值结果反映了实际工作过程的一般规律。
    Abstract: In order to simulate the three-dimensional dynamic opening process of parachute system in a finite mass situation, a common flat circular parachute, the C9 parachute, is studied in this work. The working process (from inflating to dropping) of the C9 parachute is studied by using LS-DYNA based on the finite element theory. The calculation results are also verified by dropping test. The structure change and flow field change are obtained. Especially, the velocity and the acceleration of payload, which can reflect the deceleration characteristics of a parachute system, are also obtained by calculation in this work. Then the interrelation between dangerous section, overload and canopy shape is analyzed. The results show that the ALE method, a fluid-structure interaction method, can predict the deceleration characteristics and dangerous section during parachute opening. The results can reflect the general working laws of parachute in practice, and the method in this work can help determine the design or optimization of aerodynamic deceleration systems.
