摘要
通过对卫星—天线系统的物理模型进行分析,提出了卫星—大型天线系统固有模态的有限元分析模型,并在此基础上进行了系统若干低阶模态的分析。研究工作不仅为天线结构设计提供了固有频率与振型的分析结果,而且进一步为天线结构的优化设计和弹簧力的优选提供了理论基础。
On the base of the physics structure, a finite element model for satellite-space antenna system is established. The modal analysis is accomplished by Finite Element Method. The system' s natural frequencies and modals are calculated by ANSYS software, the results supply a theoretical foundation for optimization design of space antenna structure and reasonable selection of the antenna spring force.
