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-web system woven by lightweight and pliable rope is a concept proposed for capturing non-cooperative target on orbits, and it has a great application prospect in dealing with space debris and dead spacecraft. After being thrown from a platform, it forms unstable configuration in space. Its deploying performance is greatly influenced by initial parameters. The optimization of parameter matching is a key technology for the space-web system design and test. The paper proposes error-tolerance as a quantitative description about the capturing performance of space-web system and establishes an optimization mathematical model where error tolerance is the objective function. Take capturing a target in a certain distance as an example, the Isight and ANSYS/LS-Dyna are combined to solve the mathematical model and the optimal design is obtained. The simulation of the optimal design verifies the validity of optimization model. Finally, the stability of the optimal design is discussed by orthogonal experiment and range analysis. The research provides some reference for the design of space-web system, the system tests on the ground and in space and the application of the space-web in the future.

Key words: space-web system, parameter matching, optimization model, error tolerance, DOE
