群伞减速系统刚柔耦合动力学建模与分析
Rigid-flexible coupling dynamic modeling for parachute cluster deceleration system
摘要
Abstract
The parachute cluster deceleration system is widely used by the new generation reusable manned space-craft,and dynamic analysis and evaluation of the parachute cluster system is an important task in the design and analysis of spacecraft deceleration missions.A multi-stage,variable structure and high-dimensional rigid-flexible cou-pling nonlinear multi-body dynamics model is established for the spacecraft parachute deceleration system.The char-acteristics of the system dynamics model are analyzed,and it is pointed out that the dynamics of the parachute cluster deceleration system have the dynamics properties of complex system.The dynamics and motion parameters of space-craft,the drogue,and the main parachute are simulated and analyzed,and the results of Monte Carlo uncertainty simulation are summarized.The simulation and analysis results show that the established rigid-flexible coupling dy-namic model can accurately simulate the working process of the parachute cluster deceleration system and the dy-namic behavior of parachute group collisions.Finally,the existing problems and future developments in the dynamics of parachute deceleration systems are also discussed.关键词
