摘要: 借鉴降落伞“先拉出、后展开”思想,提出一种空间绳网二级发射模式,并建立了数值仿真模型。该发射模式将绳网拉出展开过程分解为拉出和展开两个步骤,进行分步控制,保证了绳网规则、有序地拉出,避免了绳网拉出展开过程中的缠绕、穿透和打结等问题。将数值仿真结果与地面试验数据进行对比,验证了该模型的有效性和可用性。空间绳网二级发射模式的提出与仿真模型的建立为空间绳网发射优化设计提供了一种参考途径。

Abstract: A two-stage projection scheme of space nets is proposed by using “outstretching first and opening later” idea in parachute inflation process, and a numerical simulation model is developed. In the proposed scheme, the projection process of space nets is divided into two successive courses: the first-stage of outstretching course and the second-stage of opening course, through which the process is controlled step by step to pull out the space nets regularly and ordinarily, and avoid their twining, penetration and knotting problems. Through a contrastive analysis of the numerical simulation result and the experiment result, the numerical simulation model is tested and verified. The two-stage projection scheme of space nets and the numerical simulation model developed in this paper provide a reference way to carry out optimization design of space nets.
