摘要：
The simulation results of the deployment dynamics of non-conductive space tether are inconsistent with the actual situation due to the lack of deployment friction data. To solve this problem, the deployment friction measurement experiments of non-conductive space tether are conducted based on a ground tether deployment platform, the effects of different materials, diameters, winding direction, and deployment velocity of tether on the deployment friction are studied, the main factors affecting the "ball effect" unstable phenomenon during the deployment process are clarified, and the quantitative relationship between the deployment friction and the deployment conditions is determine. By further study of tether deployment dynamics simulation, it is found that deployment friction has a significant influence on the tether deployment: for a 500 m long tether, the difference between the deployment duration without considering deployment friction and the deployment duration with considering deployment friction is about 20% at an initial deployment velocity of 2 m/ s. © 2024 China Ordnance Industry Corporation.
