空间飞网发射动力学建模仿真研究与地面试验

Dynamic Model and Simulation of Orbital Net Casting and Ground Test

空间飞网是近来提出的一个创新的空间系统概念,在空间碎片处理和在轨服务方面具有独特的应用潜力。针对飞网系统的发射过程,利用建模仿真和地面试验两种手段进行了研究,建立了飞网发射的集中质量模型,设计了基于燃气助推质量块的飞网发射地面试验装置,开展了多次飞网发射试验。地面试验结果与模型仿真结果基本吻合,说明所建立的动力学模型可用于空间飞网系统设计。

Orbital net capture is an innovative mission concept, and has special potential on space debris disposal and OOS （onorbit service）. Dynamics of orbital net casting is a key technique of the orbital net capture system design and application, for which two major feasible investigation means have been suggested： dynamic modeling, simulation and ground test. Based on dumped-mass model, a model of the system dynamics was derived, and a ground test device was designed to verify the simulation result. The comparison of several ground tests and simulations shows that the model can be used to design orbital net capture systems. Relevant pictures of ground test and simulation were presented.
