空间带网抛射展开参数分析

随着空间碎片对航天器及航天员威胁的日益增加,采用飞网的空间碎片清理技术已成为研究热点。本文采用强度更高,缠绕现象少的空间带网代替传统飞网。基于弹簧质点法采用MATLAB进行了抛射展开过程仿真。为了能更好的模拟带网发射过程,本文提出了空间带网抓捕效果评价指标。并对带网的结构参数进行敏感性分析,讨论结构弹簧弹性系数和剪切弹簧弹性系数对展开过程的影响。其次对发射参数进行分析,讨论发射速度、发射角度和质量块质量对展开过程的影响,为带网的抛射展开提出参数选取依据。结果表明较大弹性系数有利于带网展开过程,发射时不宜选取过大发射速度、发射角度及质量块质量。

Parameter analysis of space belt net emission expansion

With the increasing threat of space debris to spacecrafts and astronauts, the space debris clearance technology using flynet has become a research hotspot. In this paper, the space belt net with higher strength and less entanglement is used to replace the traditional flying net. Based on the spring particle method, MATLAB was used to simulate the ejection expansion process. In order to simulate the launching process of belt net better, this paper puts forward the evaluation index of the capture effect of space belt net. The influence of spring elasticity coefficient and spring elasticity coefficient on the unwinding process is discussed. Secondly, the launch parameters are analyzed, and the influences of launch velocity, launch Angle and mass block mass on the launch process are discussed. The results show that the larger elastic coefficient is beneficial to the belt network development process, and it is not suitable to select the large launching velocity, launching Angle and mass.
