| 摘要: |
| 研究了降落伞一物体系统的空间运动。假定降落伞和物体都有6个自由度, 两者通过吊带连接起来。推导了物伞系统运动的非线性微分方程, 运动方程中没有考虑伞绳和吊带的弹性。用所得数学模型分析了减速伞回收系统的动力特性, 给出了仿真计算结果。 |

| Abstract: |
| The three-dimension motion of a parachute and payload system is studied. Both the parachute and payload are assumed to have six degrees of freedom. They are coupled by a riser. The nonlinear differential equations of motion for a parachute-payload system are developed, which model the parachute suspension lines and the riser as inelastic elements. The resulting math model is then applied to analyze the dynamic performance of a drogue parachute recovery system. The simulation results are presented. |
