摘要

摘要: 空间环形可展开天线借助于贯穿在杆件中的绳索的收卷完成展开,为了能精确测定已收卷绳长,使绳长作为天线展开程度的有力判据,文中设计了一种带绳索排布管理的动力展开机构。该机构利用原有展开机构的动力源,经过齿轮变速箱传动,由凸轮机构将展开电机的单向转动转化为过绳滑块的往复运动,来引导绳索在卷绳轮上按照一定的规律整齐排布。动力学仿真分析和功能试验,均证明该机构可以在承受一定负载的情况下平稳运行,绳索排布的效果良好。

Abstract: Hoop truss deployable antenna(HTDA) is deployed by convolving the rope throughout the pipes. In order to accurately measure the length of rope which has been convolved,and to make the length of rope serve as a criterion of the antenna deployment,a deployable mechanism which can array the rope regularly is designed. The mechanism uses the original electromotor to draw the rope arraying regularly on the wheel by transforming the rotational movement of electromotor into arthrodia reciprocating in a beeline through a gear-box,The simulation analysis of dynamics and the function experiments prove that the mechanism can run steadily with payload and the rope can be arrayed regularly.
