摘要
空间可展开机构在航天器中取得了广泛的应用,其研究也成为一个热点问题。星载可展开天线是卫星结构的重要组成部分,其实现技术直接影响到卫星的技术水平。其发射时折叠为一个可以接受尺寸的系统(收拢状态),而在达到预定轨道后,通过展开机构按设计的方式解锁、展开、锁定,展开成为天线(展开状态)。根据星载可展开天线的设计要求设计出一种天线方案,并针对方案进行了基于ADAMS的运动学仿真分析,最后针对运动过程进行优化以增加展开过程的平稳性,为星载可展开天线的深入研究提供了有价值的参考。
Space deployable mechanism has been widely used in the spacecraft, drawing more and more attention on its study. Deployable spaceborne antenna is an important part of satellite＇s structure, and its technological level has a great influence on that of satellite. It can fold into a system of accepted size, can unlock, deploy and lock when reaching orbit with the help of designed deployable mechanism, and can fi- nally deploy into an antenna. This paper designs a plan according to the requirements of deployable spa- ceborne antenna, and carries out kinematical simulation analysis based on ADAMS. Finally, to improve the stationarity in deployment process, optimization of motion process is carried out, which provides useful ref- erences to a further study of space deployable mechanism.
