摘要: |
本文分析了冲压式翼伞开伞的特点,提出了一个展弦向二维开伞模型,建立了伞衣的径向运动方程。在推导系统运动方程和分离体运动方程的基础上,建立翼伞开伞仿真状态方程,用龙格-库塔法求解,给出开伞充满时间、开伞动载、翼伞速度和位置坐标等参数的变化值。本文提供的开伞仿真计算软件包,可用于各类冲压式翼伞的开伞仿真计算。 |

Abstract: |
In this paper,based on analysis of parafoil opening properties,two-dimensional opening model of parafoil is presented. canopy radial equation of motion is established. At the same time. parafoil system is assumed to be a two-particle-elastic rod model,then the equation of motion for parafoil system, canopy, and payload is derived. Finally,parameters such as filling time, shock force, inflow velocity, etc. are obtained using computer simulation. The simulation program can be used in some parafoil design. |
Keywords: parafoil,opening simulation,filling time,opening force |
