摘要
建立一种思路清晰、求解方便易行的降落伞-返回舱系统的动力学模型是研究降落伞-返回舱系统动力学特性的基础。文章从一般刚体动力学方程入手,结合刚体的运动学方程,建立了稳降及着陆阶段舱-伞系统的动力学模型,并与空投试验的一些测试曲线进行对比,证明了本模型的正确性和有效性。
Establishing a dynamics model is the base to research the dynamics characteristic of parachute-return capsule system, Therefore, this paper starts with common rigid body dynamics equation, integrating with rigid body kinematics equation, and then establishes the dynamics model of main parachute-return capsule system in descending-steady and landing phase. Compared with some testing curve of airdrop experiment, the current model is proved accurate and effective.
