当前空间非导电绳系释放过程因摩擦力数据缺乏，导致释放动力学仿真结果不能有效反映真实情况。为此，基于绳系地面释放平台，开展非导电绳系释放摩擦力测量实验，研究了系绳材料、直径、缠绕方向和释放速度对系绳释放所受摩擦力的影响，阐明非导电绳系释放过程影响球形效应不稳定现象的主要因素，确定非导电绳系释放摩擦力与释放条件之间的定量关系。进一步建立考虑摩擦力的绳系释放动力学模型。仿真结果表明，非导电绳系释放摩擦力对释放过程影响较大，对于500 m长的系绳，初始释放速度为2 m/s，在未考虑释放摩擦力时，绳系释放完成时间与考虑摩擦力的实际情况相差约20％。
Effect of Friction on Deployment Dynamics of Non-conductive Space Tether
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.
