摘要: 建立了12自由度的物-伞系统动力学方程,采用三个欧拉角来描述悬挂体的运动姿态,总结了悬挂体姿态运动的5种基本模式和3种典型的复合运动模式;并给出了运动模式的量化描述、各个模式与刚体姿态运动欧拉角描述之间的关系。通过算例说明上述结果具有一般性,对于回收系统悬挂体的姿态分析有参考价值。

Abstract: 12-degree dynamic model of body-parachute recovery system was established,in which pitch,yaw and roll were used to describe angular motion of the suspended body.5 basic modes and 3 representative composite modes with quantitative characteristics were summarized,and the relation ship between specific modes and corresponding angular description was presented.Simulations and analysis show that this method can be used in angular motion analysis of generic suspended body.
