星载环形天线重力补偿新方法

摘要/Abstract

摘要： 针对环形天线地面展开试验中由吊丝非铅锤效应引起的重力补偿不足和吊丝附加水平横向力等问题，提出了一种吊丝主动水平定位与运动的重力补偿方法。对环形天线展开过程进行运动学分析得到了各桁架节点水平位移与桁架展开角的函数关系，进而实现天线展开过程中滑轮车对桁架节点位置的精确跟随；对环形天线展开过程进行力学分析，得到了各个吊丝的配重质量；基于ADAMS软件对所提重力补偿方法和吊丝配重法进行对比分析，验证了方法的合理性和正确性。

Abstract: To solve the problems of the deviation of slings and the deficiency of vertical force caused by non plumb-bob effects of slings in the experiments of perimeter truss deployable reflectors in space orbit, a gravity compensation method was proposed herein with active horizontal positioning and moving slings. Firstly, the relationships between the horizontal displacement of truss nodes and truss deployment angles were obtained by kinematic analyses of the deployment processes, so that the positions of the truss nodes could be followed in deployment processes accurately. Furthermore, static mechanics analyses of the deployment processes were carried out to determine the masses of counterweights. Finally, the rationality and correctness of the proposed method were verified by comparing with the hanging wire counterweight method based on ADAMS.

Key words: perimeter truss deployable reflector, gravity compensation, kinematic analysis, active positioning
