【摘要】：由轻质软绳索编织而成的空间飞网是为非合作目标捕获而提出的空间系统概念,在空间碎片和废弃航天器处理方面具有很大的应用潜力。从平台抛射出后,飞网在空间形成不稳定的网形,且网形变化规律受初始参数设计的影响较大。针对空间飞网系统设计与试验中系统参数匹配问题,本文提出以容错值作为飞网展开性能的定量描述,从捕获任务的层面,建立面向捕获容错的空间飞网系统参数优化数学模型;以抓捕固定距离、确定大小的目标任务为算例,联合Isight优化平台与ANSYS/LS-Dyna求解,得到飞网系统最优参数匹配,算例仿真结果表明结果的适用性;最后,利用试验设计和极差分析方法验证最优点的稳定性。研究的模型与方法为开展空间飞网系统地面及空间试验等工程应用提供理论依据。
[Abstract]:Space net made of lightweight soft rope woven space system concept proposed for non cooperative target acquisition, has great potential in space debris and waste disposal. The spacecraft from the platform project, the formation of net net shape unstable in space, and the variation of net shape is affected by initial parameter design large. According to the system design and test system for space net parameter matching problem is proposed in this paper to value net expansion as a quantitative description of the fault-tolerant performance, from the capture task level, establish the mathematical model of optimization of system parameters for space net capture system fault tolerance; to arrest a fixed distance, determine the target task size as an example, combined with Isight optimization platform and solution of ANSYS/LS-Dyna, the optimal parameter matching net system, simulation results show that the applicability of the results; finally, using experimental design and range analysis The advantages of the method is verified. The stability of the model and method of the research provides a theoretical basis for the development of ground space and space net system testing and other engineering applications.
