摘　　要：针对使用粘附抓捕方法进行空间非合作目标捕获能力界限不清的问题,对具有Stewart碰撞缓冲平台的服务航天器的粘附抓捕动力学建模问题展开研究,提出了基于混合坐标多柔体动力学建模方法、罚函数接触建模方法和Cohesive模型的粘附捕获动力学模型;在此基础之上,对粘附捕获过程中的动力学行为仿真分析,探究碰撞速度、缓冲器阻尼对系统动力学行为的影响。仿真结果表明:随着碰撞速度的增加,粘附捕获失败的可能性会增加;增加缓冲器阻尼可提高捕获的成功率。To solve the problem that the boundary of the capture capability of the non-cooperative target in space is unclear,the dynamic model of capturing the service spacecraft with Stewart colli-sion buffer platform was studied,and the dynamic modeling method of flexible body based on hybrid coordinates,the contact modeling method of penalty function and the Cohesive capture dynamic model were proposed.On this basis,the dynamic behavior of adhesion capture process was simula-ted and analyzed to explore the impact velocity and buffer damping on the system dynamics behav-ior.The simulation results showed that the probability of adhesion capture failure increased with the increase of collision velocity,and the probability of capture success increased with the increase of buffer damping.
